Since I put the A6 up for sale i have been driving the Corrado more and more, and now exclusively as the Audi is gone. I know that VW's, especially Corrado's aren't known for their reliability, but mine (knock on wood) has been relatively good to me. The one thing that used to be a recurring issue was overheating, and now that I have replaced almost everything in the cooling system (radiator, hoses, thermostat, water pump, etc) the car is great. My Corrado is a 1990 so it's almost old enough to drink, and because of its age, trim pieces and such have been known to disassemble themselves for no good reason (well its probably due to my solid motor mounts, boost underdrive pulley, and exhaust system that rattles everything on the car). If I was in the market for a Corrado again, I'd probably be looking for the VR6 version, as the G60 chargers have been known to grenade themselves without any warning, Mine has been good to me so far, but the G60 has been described in many a forum as a "ticking time bomb". The VR6's can have issues too, I know they have been prone to oil leaks/burning problems (but most people on here are probably used to that by now) and have also been known to go through head gaskets. The other thing about Corrados is that due to the styling, you'd think that it is a fast car, and in comparison to other VW's of the same vintage it is a bit faster, but I would by no means consider the 'Rado fast. You can make them fast, but you are going to spend a lot of time and money to get them there. I bought the car because I liked the styling more than the performance, and for what I use it for it fits the bill perfectly.
My current thoughts are to buy my friends corolla (for reliability and gas mileage's sake) and then sell the Corrado for more than I will buy the Corrolla for, to help supplement my VX fund, and have something that is KNOWN for reliability.
