Interesting perspective... thanks.That's a great question. The corrado certainly doesn't get driven nearly as much, but then again, ever since I got my first new car in 2006, I have started using it less for street driving. Until the mustang, it used to be that if I wanted a shot of speed, I would take the corrado out because I do have a blower on it. And for how much it weighs, what it puts out, and the short gearing, the car is a total blast and much faster than my old GTI or crossfire. Of course, the mustang is going to be a fair amount faster.
The problem with the corrado is that I don't have the dampers well matched to the springs, so the car is REALLY bouncy right now. So one of my goals is to get the dampers re-valved if possible. Hopefully that will make the ride a bit better on the street. It's generally not a problem on the track however--for good reason, since most tracks have pavement that's in better condition than what's on the street. With how I've set up the corrado, it's much happier and more fun the faster and harder you drive. It's rather disappointing and somewhat annoying to drive at normal speeds.
So for street driving, the mustang is in another world. It's simply a better car--it's faster and the suspension is set up better for the street. For the track? I haven't had the mustang out on a track day yet. But I would say that for any sort of aggressive, back road type of adventure, I'd much rather drive the corrado. The corrado has more than enough power and the suspension is excellent when driven hard on fairly smooth roads. There is more front end bite on the corrado than the mustang, currently, at least when driven up to say 8/10's. There's also a crispness to the way the corrado change directions that is simply lacking in the stock mustang. A lot of that has to due with the corrado weighing a good 700-800 lbs less and having a much stiffer suspension.
So what I end up with are two different tools for two different jobs. Having said that, I wouldn't be surprised if the mustang was faster around the track, but the corrado would be more fun to drive in that ennvironment.
