supagaurds not as good as lifeshine (autoglym) we do both... charge around £299 for it, actaully costs £60 plus valeters time... is worth it,if only gor the interior treatment, technically is a rip off at that price but use it as a bargaining tool cos usually we will chuck it in for cost or free to close a deal( with our lifeshine you get a decent pack of cleaning kit aswell for free)
