Don't buy a used VW. Replacement parts cost an arm and a leg.
Also, don't buy a used Lexus or Infiniti. Even though they share a lot of parts with the normal Toyotas and Hondas, for some lame reason Lexus and Infiniti parts tend to carry a premium, even though they're the same damn part.
Anyways, for 9K, you might be able to buy a brand new Kia.
Seriously though, can't go wrong with a Honda or Toyota.

The cake is a lie.
