Enjoying New BMW
 Purchased in Feb.  Terrific ride - very comfortable.  The oversized sunroof is a real plus.  Ordered Premium Package, rear side airbags, mats, heated front seats, metallic color.  Nice ride:  car performs beautifully.  So far, shows I'm only getting 15.6 miles to gallon, although alot of street driving.  No hesitation as mentioned in another post.  Very powerful and sensitive brakes.  This is a feature added as I read it's designed to perform right away.  Very roomy although rear has hump in middle seat.  The technology over just a few years ago is amazing.  Had another customer in car wash actually strike up conversation about how nice the car is.
