Had mine basically since 1994.Still love it as much as I ever did as its been very very reliable.Bear in mind that mine is only used for trackdays,about 1,000 miles a year,but I was told that equals about 10,000 road miles. But I'm getting a little fed up with its power output,its very annoying having pri*ks in Cossie's holding you up on the bends only to piss off into the sunset on the straights,then hold you up again at the next bend!! But as much as I'd love a trackday Cossie,if it ever blew up I wouldnt have the money to fix it,so the RST is staying put for a while longer.Regards,Micky
