I may be slightly bias here, as having owned one for nearly 5 years, I'd get the Coupe
I'm sure the Hondas are great cars and scream with their VTEC, but they won't "feel" that fast. The 20VT Coupe has a very flat torque curve from 2,500rpm and feels very fast. Standard for standard the Honda would probably be the better handling of the two, but a Coupe 20VT would leave it in a straight line (0-100 is 14.5 secs). If you decide to have more power the turbo'd Coupes are very easy to tune, but the Honda's aren't.
It doesn't take much to improve the handling, a Fiat Coupe 20VT won the FWD handling TOTB 2008 & 2009, up against Novas and Civics - (much lighter cars).
One thing to bear in mind with the Coupe is they require maintenance, the youngest car will be 12 years old, and so check through the service history carefully for evidence it's been looked after. The oil needs checking every 500 miles.
The best thing to do is sign up to the Fiat Coupe Owners forum. There is a *vast* amount of information and knowledge, and it's a very friendly and helpful place.
