Yeah, I heard that the engine in the GTs were mighty loud. Personally, I like that. A lot of people don't. The Mustang GT isn't exactly your average car though. A mod or two and you can have a 400 horsepower beast that will leave 90% of the cars out there in your tire smoke. You've GOTTA love that.
I never was much of a mustang guy once I bought my first Trans Am in 1994, but before that, I had a 1977 Mustang II Cobra. It was an EXTRAORDINARILY fast car. It wasn't the prettiest thing out there, but it ate other cars alive. I went through a set of tires in two weeks when I first bought it.
Once I got the Trans Ams, there was just no looking back. Fast was an understatement for all three of 'em.
Other than the current Pontiac GTO, there's really no american-made sportscar that I'd rather have right now than the mustang. The mustang runs a VERY close 2nd to the GTO, but you just can't top 405 horsepower with a bone stock car. Slap some better exhaust and intake on there and you're up around 450, add a tuner and you'll be up around 465 or so. That much horsepower in a car as small as a mustang or GTO makes me drool.
Anyway, if you get the mustang Tater, good luck and have a lot of fun!!!
