I have a 4C and just got the 400 (in gearshift) about 10 days ago. I have bunch of cars, (almost none are stock) and my 4C has had a few mods (tuned engine and tranny, airbox & throttle controller), and it is a blast to drive. Been a long time since I have driven an Elise so hard to compare. The 400 though feels like a luxury car is comparison to the 4C. Mine has less than 60 miles on it, still breaking it in.
