make sure you get one that is BONE STOCK.
trouble areas:
- lower intake manifold gasket leaks
- transmissions get tired if beat on and go away quickly
as far as potential, depending upon money spent and in what areas you can either have a 14 second car or an 11 second car. with a thousand dollars into it (in the RIGHT mods, not what you THINK would work on another car) you might be pushing mid-high 13s if you can drive very well. traction is the name of the game with these cars. with a few thousand dollars you can easily run high 12s, again if you can drive.
