What are the best Used Sports Cars under 30K?? AUDI, BMW, Porsche, Benz???

Porsche Boxster or Cayman, try to get an S model if your looking for perfomance.

That was one of the options, from what I've found you have to replace some bearing in the engine to an aftermarket ceramic one otherwise the engine blows when it starts to get higher milage.

Got with a Vette... more bang for your buck... may not have the 'snob appeal' of the Germans, but definitely a better car for the price - not to mention when going for a road trip, the Vette puts up like 27 MPG - can't get that from the others...

The key to any one of these cars is to find one that's been properly maintained, backed up with complete records. If the owner doesn't have a thick file of paperwork proving what's been done, that you have to assume the car has been neglected from a maintenance standpoint, and abused from a driving standpoint. RUN from any sports car that lacks paperwork.
