I bought a car from them and it was a good experience and a great car. (94 Cobra)

But really if you want a car that is going to be a play toy that you just drive for fun get something with a big engine. I know that sounds stupid but people forget the more displacement you have the easier it is to go fast.

If you were on a budget of 10,000 or so I would do this.

Start out with a 96-98 4.6 Rustang
-get on one of the trillions of mustang forums, I recommend turbomustangs.com, and get a cobra crank and some forged rods and pistons. You can probably get them used at an awesome deal.
-Get a built auto for really cheap that will hold all the power you could ever want or a t 56 or something similiar like a tremec.
-New axles and lsd

You then have the basis for a serious horsepower platform

Add something like a diesel turbo because the motor will spool it (4600cc's), flip the headers, and weld a few pipes.

If you can't make a measly 650++ whp with that then you don't need to be working on cars. The same goes for LT1 Camaros. Even more displacement. I used to be really into these cars, but for what I do imports are better. And Like I said its all about what you want to do. If you wanted a DD I woulda said Honda. So I'm not biased.
