It would be a good idea to get out of the F430. My father owned an 06' spider as well, and while he took a huge hit selling it, it was the better decision. The roof on the car failed twice and bent several panels as well. The dealership informed him if it wasnt under warranty, he'd be looking at a 30k fix each time. DO NOT own an f-car out of warranty if you dont have lots of cash to burn. He sold his 06' spider in Grigio Silverstone with 8k miles for around 150k I believe... It took him awhile to find even that in our So Cal market. Good luck with whatever you decide!
