HEllo all balt owners so today was the first oil change for my 2007 ss. now i live in los angeles idk if that would matter so i get slaped with a 80 usd charge for a oil change.So just wondering is that what a real SS is priced for a simple oil change? or i got fooled? now the excuse for the charge was its supercharged wtf??? how does that matter??? any one has the same problem?
