Yep, one of the things scaring me off the Audi's and Saab's of the world is the resale value. Audi's, in particular, are culprits when it comes to having a few hundred miles and leaving a big chunk of change. Porsches seem to hold their value far, far better. I guess that's what happens when you build cars that have accelerators that have a mind of their own...
I'm in London right now, but I'm going to get out to lots when I get back to LA. I was largely surprised when looking at cars with under 1000 miles on Autotrader...looks like the bottom fell out on the TT 2.8 market, I see a few with 500 miles that are selling for around $40k. Niiiiiice.
But seriously, I'd be happiest with the Boxster S or the 356, 'cuz, well, Porsche: there is no substitute!
