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.
Its a no brainer. I would definitely go for the coupe. My dad used to have one and i regret the time he sold it. If i was a bit older i wouldnt let him do that. What a car it was its still in my head that car and i will not calm down until i buy one myself too.
What a fantastic car the coupe was
My dads coupe was the 16VT too. He used to tell me that the engine wouldnt run smooth when he started the car and was cold until it warmed up.
I was quite young when he sold it i dont remember much but i still remember the power it had and how it pulled thats still in my head
