if i had the time i would do the work myself; on my R200 i upgraded my front brakes to a set from a 620ti, swapped all the suspension to a set from a mg zr, etc. Main reason why i haven't attempted to do the work myself is that i don't have the time to do the research into the work required and then purchase all the parts and then take out a day to fix it as i am a medical student and have loads of exams in Jan.
i can understand where studabear is coming from, end of the day its big business and money has to be made. I just cant afford £320 odd to fix it when i can go somewhere else which will do the same job for a lot less.
