Were you waiting for the 997 generation of the Porsche 911 to drop below $30k? The time has now come. There are currently seven 997 Porsche 911 Carrera coupes listed on Autotrader.com for $29,XXX and one has just 80k miles.
Financing a vehicle of that age with a reasonable interest rate may be difficult, but it can be done. A credit union would be your best bet unless you've got 30 large laying around.
Now, do I sell the E46 M3 for one?
