2006 Tacoma 4cyl. Auto Access Cab SR5
 The four cyl. automatic has a tougher go of it in the Texas hills.  Here on the coast it's a good deal.  It will consistently do 28 mpg on the highway at 63mph speed.  Do not go to the larger wheels/tires or you will lose 2 mpg fuel economy.  The optional shift or automatic (2nd, 3rd or drive only) is fun to use.  I would recommend the 5 spd. manual if you want to tow with the four cyl. This long bed with the access cab can haul a lot.  The short second seat is perfect for your gear, tools, groceries, or a small animal carrier. As usual for Toyota, this truck is absolutely dependable (80,500 miles in less than 3 years, w/no issues).
