I just bought a 2003 supercharged Mustang Cobra SVT Terminator convertible for $12,500 with a lot of mileage on it (118,000). It is supposedly a rare edition, it's number 834 of 5082. I don't like the milage on it and I'm afraid that the engine is going to give out soon. One of my friend's is saying that I should have gotten the 2005 and up body style, of course I can't afford the newer Mustangs. Do y'all think this Mustang is a keeper? I have had it inspected by two certified mechanics and they both said it was a good choice. Also, about how many miles can you expcet on a full tank on a supercharged model like this one? It has 390 hp, I believe, so I wouldn't expect many miles. The only complain thus far is that the interior quality sucks even though it is in decent condition.
