If he doesn't have a basic understanding of car's especially rst's mate then why buy one? TBH we all know there not the most reliable at the best of time's etc so he doesn't know what he's chatting about but yet bought it anyway?

Sorry more fool him!

Although i done the same thing with my S1 so i'll admit i am a fool here too but i'll tell ya what anyone who buy's an RS should really read up on them i wish i had have done!
