I ran the VIN and the 07's engine is definitely in the safe zone.

Test drove it a second time and it seems a little hesitant on the initial up shift to higher gears. Considering it's the same transmission as my e430 that's a little bit unusual, probably not the best comparison. Otherwise it's a wonderful car.

Will also be driving the 08 again and then will make a final decision. There is a substantial difference in price, about $1,400.,with the 08 being higher, with slightly higher miles but seems to drive more smoothly than all the other cars I've driven, including the 07. It also has the 18 inch 10-spoke wheels which I actually like, but am not sure are worth the premium.
