If you do want a track car, like Audi's and 4WD, can I throw my recommendation in for a first Gen Audi TT?
Can be bought cheap, you know the brand and parts are easy to come by, fast when stripped with a few choice mods, and aside from straight acceleration are faster on circuit then a new RS6. Don't believe me? check my video from last month - and this is only running 250bhp at the moment and they can be tuned to 300bhp before rods and 400+ with Rods as the rest of the engine is already forged:

Bang for your buck, they are so much fun on track and more room for hairdryers when driving any other time (I jest...)
