With all this talk of swirls on new cars etc. (mine was thankfully fine when I got it) I'm very surprised that dealers aren't making the investment (in materials and training if nothing else) of their valeting bays. If nothing else, the ones that are sending out new cars to detailers could plough that money into the valeting bay and actually improve the quality of valet and their reputation.
I know timescales (per car) are sometimes limited for the valeters but at least give them the right stuff (and enough of it not to have to reuse stuff like the same cloth/drying towel etc. all day)
I know 'some' tiny scratches are almost unavoidable in a high volume valeting bay, but it's not hard to at least minimise the "washed with a brillo pad" style valeting, surely?
