I felt the same as you do now a couple of years ago. I got rid of my RS-Turbo as I couldnt be bothered with it anymore and it was just a money box. I sold it and bought a Focus RS as it gives me a performance car and comes with the benefits of a modern car. I realise you can buy faster cars and its not as quick as a 300bhp RS but I have piece of mind knowing that it will start everytime and I wont have to worry about leaving it anywhere.

I guess what im saying is, instead of having two cars-sell both and have 1 really good car that gives you performance and modern benefits.
