Never had any reliablity prob , how did have a cam belt snap after 17k and got away with it ( thank Fu<k ) . If I got another one it would be a Mk 1 and most do"s for any one buying one is a cage because there made from tin foil , sump/gearbox skid pan if it's lowered , and always leave the airbox cross over pipe but with a cossy cone filter as that removes any flat spot ,keep small wheels on it aswell , that's just a few must haves lol,
