Get the 911 turbo, if you send me a pm I will forward you the email from Porsche starting the negotiations at 9k off msrp. I would get a 1yr old porsche turbo cpoed if your looking to spend that kind of money. The car dealers are hurting and I think they have the mentality of the "real estate never goes down" people.
I used to have the 4s 996 and felt my heart sink every time a 911 turbo would lurke. I will not make that mistake again. Currently I have the 335 as a daily driver, but im looking to put the new 997 tt in the garage in the next three years for under 60k. It will be 4-5 years old, under warranty(no matter what the cost) and less than 25k miles, although I have seen some with as low as 15-20k miles. They are all beautiful cars. When your dad is done with the porsche, maybe you can pick it up!
