Lmao so it's easy to have a quick look under the car and judge the manufacture year of a track rod end or indeed whether it has excessive play? How much road grime should a track rod end have after 12 months?
Well, I can see all the parts I've replaced on my car in the last yr as distinct from the older (probably original) items. But thats totally missing the point. As I said it's not about proof, it's about reporting your suspicions. For Trading Standards/VOSA it's very very easy for them to prove
in total.
Lets say the garage invoiced 200 customers for TREs last yr. then they have to be able to provide a Unipart/ECP/other motor factor account statement for those same 200 TREs. If not, then how did they fit them. Businesses are required by HMRC/companies house to keep records so they're in the shit if they can't prove it anyway.
My point still stands that if no-one reports their experiences, these things never get started.
