I bought my 98 svt last fall for 4500. 118,000 but in mint condition. All the switches even seem like a new car. Not even any wear on the drivers floor mat, It's like they pushed it down a really big hill and steered with remote... Now its 139,856, only problem I had was a p0420 last week, besides an operator-induced cracked transmission case. It's all stock down to the air filter, and on a 7 degree day last winter I hit 154 on the speedometer. Good brakes too. Well, they will be good brakes again as soon as I replace them, but thats somewhat of an operator induced failure too.
Sorry to hear about your woes, buy a GM car and your current woes will seem like a gift, then will see trying to find another SVT tour because for the current price they are the only 4 door car with any kind of performance that doesn't suck unless you get something like a BMW or Mercedes, but get your other wallet out...
Besides, you're bitching about a problem that should be under some kind of warrantee, it's not the cars fault the mechanic messed something up.
If you want a cheap fast car you can beat to death with minimal maintanence, I suggest 85-93 mustang gt. Easy to work on too, you can pull the trans in 45 min instead of 4-5 days...
