It depends on what your looking for. Some people want an all original mustang, that has not been touched. While others are looking for a modified street car. Like I said above, I am doing a 4 cyl conversion, the reason is because I got my car for basically nothing. the body is super clean. I plan on changing everything. In my eyes there is nothing wrong with this swap because everything will be done. I am starting with a nice straight and clean chassis, and its going to be a modified street car. When I'm done I will proabably have close to 15k invested. It is a lot to invest in a car, and I know I will never get my money 100% back. But its what I want to do, and I plan on keeping the car for a long time....
(Well until I get my IROC-Z project car)
