Did the car have this problem before you bought the car? As a price, Mao (evolution R) is offering clutch replacements from $950.

Not a bad price!

As for doing it yourself, do you have some knowledge on replacing clutches? Clutches involve removing the gearbox so if you don't then i would suggest not to, especially when there not that expensive.
