I have the following questions. Thanks for reading and replying. All cars are preowned.

Choices of cars
997 TT
Gallardo
R8
Ferrari 360

Budget: $140k

Reliability
I know TT is the most suitable for DD. but how is the Gallardo, R8, 360? Can I put 8000 miles on it every year? Will it break down. What are some common problems? Maintenance? Im not looking to DD the car, but definitely drive the car at least 8000 miles per year. Can I put 10k on a Gallardo for a 2004?

Resale value
After putting 8000 miles on it for 2-3 years. Which car will have the best value?

Handling/steering
TT drives just like the S. Its not much of a difference. I m actually quite disappointed with how the performance is not much of a step above the S.

Price: Dealers told me I can only get 1% off of all the above cars. I ve heard the S can go as big as 7%. 1% is barely $2000. How much discount can I get? Porsche dealer also said New TT coupe/cab is sold at MSRP.

Performance: I only test drove the TT cab, are the other cars that much better?
