The diesel has more power at the bottom of the rev range and the gas engine more towards the top. I drove the 35d and a Q7 tdi back to back this weekend. e70 is so much more of a driver's car. The Q7 felt a lot like a GL I drove a while back. The tdi is much quieter but I feel that the amount of rubber needed to achieve that also makes the whole experience a bit soft.

Congrats on the new car Seth!

I found a nice 35d for sale but it is 200 miles away and I can't get away from the offcice this week.....hope it is still there on Friday night.
