There are many many many better cars you can buy for 13k then a srt4...
Much more reliable, better looking, not as common, with stronger engines and perform the same.
That said, I won't deny the Skittle is a fast car.
Hell I bought my Z for 7k in amazing condition. You can get very great condition ones with 70-80k on them for less then 10k.
Another car I could suggest would be some type of cobra. I am sure there are some out there in that price range. Or a vette. mmmmm <3 vettes
