Two points: 1. just returned from an 1100 kms (682mi) trip. Mostly hiway, four lane divided, and some two lane. The 35i has all the power I ever needed, and cruising in the 120 to 140 range is quiet, stable and a joy. Lots more power available if I need it. With the 8spd tranny, it's only turning about 2000rpms at 120km/h (74mph).
and 2. my previous car was an E90 M3, 28i wasn't going to cut it.
