I purchased this car recently, about the only few problems I have had with it are the battery was bad, but this is due to the fact that it was the original battery to the car. Batteries don't last forever.
The belt makes squeaking noises (I think it needs a new belt), and the brakes, which happen to still be good, make a squealing noise when I use them.
Other than that, the car has worked 100%.
This is a very fun and beautiful car to ride around with the top down. When the top is up it feels like just another semi cramped sports car and I don't get much enjoyment from it. When the top IS down, it's loads of fun and it feels like you have as much room as in a large sedan.
It seems to be pretty economical on fuel, but gives you the speed when you need it. Being a V6 and not the bigger V8, it still sounds like a sports car and it's hard not to go over the speed limit on an open highway.
It's a beautiful car with all the great addons, the mach stereo system I didn't really want, but now that I have it I'm glad it's there. The car is nice and roomy for 2 people, don't take the back seat seriously if you're going on a long trip.
The leather and design, both inside and out, is wonderful. I have only owned this car about a month and I'm already having a lot of fun with it.
My only 2 or 3 complaints would be that the emergency brake needs to have a warning to tell you it's on (you must set it in order to put top up or down), and sometimes you forget it's on and start driving.
The brakes, even though in good condition, make squeaking noises. This may be due to it sitting for a while.
The belt makes a squeaking noise when it's humid or wet outside, and makes the car sound like a 1980s junk car.
