we completed the acquisition of certain assets of effingham truck sales , inc. , which included international commercial vehicle dealerships and idealease commercial vehicle rental and leasing business in effingham and mount vernon , illinois . 201 5 outlook we expect demand for class 8 trucks will remain strong during 2015 as freight activity is expected to remain strong in most sectors . we also expect our aftermarket services revenue to remain strong during 2015 with continued demand for maintenance and repair of aging vehicles . however , the recent drop in oil prices will significantly decrease demand for commercial vehicles and aftermarket services from our customers in the oil and gas exploration and production industry , which have represented a significant portion of our revenue in recent years . we expect class 4-7 new truck sales will remain strong in 2015 as medium-duty fleets upgrade to new equipment , and longer lead times from class 4 through 7 oems drive the need for ready-to-roll inventory . according to a.c.t . research co. , llc ( “ a.c.t . research ” ) , a truck industry data and forecasting service provider , u. s. class 8 retail sales are estimated to reach 263,500 units in 2015 , a 17.6 % increase over 2014. u. s. class 4-7 retail sales are estimated to reach 206,500 units , up 3.4 % over 2014. we remain focused on positioning our company for long-term success , while continuing to deliver strong and consistent financial results . industry experts believe that the primary drivers for growth in the u.s. commercial vehicle industry during 2015 will be low interest rates , rising consumer confidence and good credit availability . key performance indicator absorption ratio . management uses several performance metrics to evaluate the performance of its commercial vehicle dealerships , and considers rush truck centers ' “ absorption ratio ” to be of critical importance . absorption ratio is calculated by dividing the gross profit from the parts , service and body shop departments by the overhead expenses of all of a dealership 's departments , except for the selling expenses of the new and used commercial vehicle departments and carrying costs of new and used commercial vehicle inventory . when 100 % absorption is achieved , all of the gross profit from the sale of a commercial vehicle , after sales commissions and inventory carrying costs , directly impacts operating profit . in 1999 , our commercial vehicle dealerships ' absorption ratio was approximately 80 % . we have made a concerted effort to increase our absorption ratio since 1999. our commercial vehicle dealerships achieved a 117.8 % absorption ratio for the year in 2014 and 114.0 % absorption ratio for the year in 2013. critical accounting policies and estimates our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements , which have been prepared in accordance with u.s. generally accepted accounting principles . the preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period . there can be no assurance that actual results will not differ from those estimates . we believe the following accounting policies , which are also described in note 2 of the notes to the consolidated financial statements , affect our more significant judgments and estimates used in the preparation of our consolidated financial statements . inventories inventories are stated at the lower of cost or market value . cost is determined by specific identification of new and used commercial vehicles inventory and by the first-in , first-out method for tires , parts and accessories . as the market value of our inventory typically declines over time , reserves are established based on historical loss experience and market trends . these reserves are charged to cost of sales and reduce the carrying value of our inventory on hand . story_separator_special_tag other income increased $ 6.7 million , or 57.5 % in 2014 , compared to 2013. other income consists primarily of the gain on sale realized on trucks from the lease and rental fleet , document fees related to commercial vehicle sales and income from cctts , our joint venture . gross profit gross profit increased $ 184.0 million , or 32.2 % , in 2014 , compared to 2013. gross profit as a percentage of sales decreased to 16.0 % in 2014 , from 16.9 % in 2013. this decrease in gross profit as a percentage of sales is a result of a change in our product sales mix . commercial vehicle sales , a lower margin revenue item , increased as a percentage of total revenues to 67.6 % in 2014 , from 66.2 % in 2013. aftermarket services revenues , a higher margin revenue item , decreased as a percentage of total revenues to 27.8 % in 2014 , from 29.2 % in 2013 . 32 gross margins from our aftermarket services operations decreased to 36.0 % in 2014 , from 37.3 % in 2013. gross profit for the parts , service and body shop departments increased to $ 473.3 million in 2014 , from $ 368.3 million in 2013. historically , parts operations gross margins range from 27 % to 28 % and service and body shop operations range from 67 % to 68 % . gross profits from parts sales represented 55 % of total gross profit for aftermarket services operations in 2014 and 2013. service and body shop operations represented 45 % of total gross profit for aftermarket services operations in 2014 and 2013. we expect blended gross margins on aftermarket services operations to range from 35.0 % to 36.0 % in 2015. gross margins on class 8 truck sales increased to 7.1 % in 2014 , from 6.8 % in 2013. in 2015 , we expect overall gross margins from class 8 truck sales of approximately 6.5 % to 7.0 % . we recorded a charge to cost of sales of $ 3.5 million to increase our new heavy-duty truck valuation allowance in 2014 , compared to $ 3.9 million in 2013. gross margins on medium-duty commercial vehicle sales increased to 5.6 % in 2014 , from 5.2 % in 2013. it is difficult to accurately forecast gross margins on medium-duty commercial vehicles because gross margins vary significantly depending upon the mix of fleet and non-fleet purchasers and types of medium-duty commercial vehicles sold . for 2015 , we expect overall gross margins from medium-duty commercial vehicle sales of approximately 5.0 % to 5.5 % , but this will largely depend upon the mix of purchasers and types of vehicles sold . we recorded a charge to cost of sales of $ 3.9 million to increase our new medium-duty commercial vehicle valuation allowance in 2014 , compared to $ 3.7 million in 2013. gross margins on used commercial vehicle sales decreased to 9.0 % in 2014 , from 9.2 % in 2013. we expect margins on used commercial vehicles to range between 8.0 % and 10.0 % during 2015 depending upon general economic conditions and the availability of quality used vehicles . we recorded a charge to cost of sales of $ 9.7 million to increase our used commercial vehicle valuation allowance in 2014 , compared to $ 5.3 million in 2013. gross margins from truck lease and rental sales decreased to 13.9 % in 2014 , from 15.7 % in 2013. we expect gross margins from lease and rental sales of approximately 14.5 % to 16.5 % during 2015 , as we expect to continue to grow our lease and rental fleet . our policy is to depreciate our lease and rental fleet using a straight line method over each customer 's contractual lease term . the lease unit is depreciated to a residual value that approximates fair value at the expiration of the lease term . this policy results in the company realizing reasonable gross margins while the unit is in service and a corresponding gain or loss on sale when the unit is sold at the end of the lease term . finance and insurance revenues and other income , as described above , have limited direct costs and , therefore , contribute a disproportionate share of gross profit . selling , general and administrative expenses selling , general and administrative ( “ sg & a ” ) expenses increased $ 123.3 million , or 27.4 % , in 2014 , compared to 2013. this increase is primarily due to acquisitions that have occurred since the second half of 2013. sg & a expenses as a percentage of total revenues decreased to 12.1 % in 2014 , from 13.3 % in 2013. sg & a expenses as a percentage of total revenues have historically ranged from 10.0 % to 15.0 % . in general , when new and used commercial vehicle revenues decrease as a percentage of total revenues , sg & a expenses as a percentage of total revenues will be at , or exceed , the higher end of this range . for 2015 , we expect sg & a expenses as a percentage of total revenues to range from 12.0 % to 14.0 % and the selling portion of sg & a expenses to be approximately 25 % to 30 % of new and used commercial vehicle gross profit . in 2015 , we expect the general and administrative portion of sg & a expenses to increase by approximately 5.0 % to 10.0 % . depreciation and amortization expense depreciation and amortization expense increased $ 10.9 million , or 36.3 % , in 2014 compared to 2013. this increase is primarily due to acquisitions that occurred in 2013 and the construction of new dealerships and dealership expansions . in addition , in 2014 we
