13k for an srt is cheap in my opinion. It is a buyers market.
All the obvious used car stuff is the same. Look it over good.
If you use the search feature you can find lots of info on common problems and how to fix them.
Parts are not cheap. Sometimes it can be cheaper to buy the best example you can afford.
Good luck in your search and I would reccomened checking out the private cars for sale area here on the forum.
If you buy one off a member you may be able to get more history on the car.
