Just had my 24k service done on my 172 and luckliy nothing needed doing so it "only" cost me £212.
Thing is according to the service report my front tyres have 7mm tread left, rear 8mm tread left and the spare 8mm. Only problem is my spare tyre is actually one of my old front ones and I know for a fact it has less than 2mm left. Now I think about it they did same on my 12k service.
Whilst I appreciate this isnt a big issue, because my car knowledge is very limited it makes me wonder what they actually do do during the service. Do you reckon I should mention it the garage?
Plus they didnt even clean it which they normally always do.
