Actually, 996 Turbo is a doable deal. The engine has proven to be MORE reliable than the base 996 engine. And, from first hand experience, it is a BLAST to drive. Marginally more expensive to maintain than a regular 911.
Very very nice car, I would highly recommend one, and the resale has held up rather well.
BTW- I am located in Carlsbad and I deal in pre-owned Porsches. If you want, I can help you find a cherry Turbo. Let me know if I can assist and I will be happy to do so.
