Agree with what you guys are saying.
My car was not used in anger for 3 years (i still drove it occasionally), as i knew that certain jobs had to be done before i could really do what i wanted with the car, i toyed with selling the car, or attempting to sell the car, but everytime i get in it and drive it, it becomes so refreshing and the buzz i get is simply awesome.
The amount of people that say "wow nice car m8" or something simular made me feel really proud of what my £££s created.
You also have to remember that these cars are now 15ish years old for some, and parts will be hard to find, but with some patience, focus and determination i think that most people will be able to come through at the other end.
Personally i would never use ebay to buy anything for my cossie, and would only go to tuners who you know you can rely on. In my case MADevelopments. But there are other very good tuners out there, can they not source these parts??
Just my view, hope you get what you need sorted.
