hi all one of my mates is thinking of getting an s60R around the 04-05 reg and he was just woundering what the most common issues are (if any) and things to look out for? also he would want to tune it a little to around the the 400hp mark so the stages in doing this would be helpfull if anybody knows? just like peoples opinion on it and also if anybody knows of any for sale?

cheers guys
