This thread reminds me of the POS picasso clutch issue about a year ago (discussed on OOF)
I remember there being warnings on the clutch cowboys invoice about returning @ 500 miles to have the clutch checked and again @ 1500 IIRC
Fortunately ,for the case , the gearbox parted company with the engine

within the 500 miles and was returned, it went back twice for them to fix ,this was due to missing bolts,clearly not tightened or not fitted .due to the lack of earth path via the gearbox to the starter motor, it also fried all the ECU loom etc effectively writing off the car.I had to take photos and get an engineer's report
after months,lots of emails,phone calls etc and legal threats , the matter got resolved,
because the £760 bill for the work had been paid by credit card, the credit card company refunded the bill, plus £1000 to find a replacement vehicle, plus £500 for expenses for hire car,etc etc plus we kept the picasso and scrapped it (another £160 for the kitty) ,they then pursued the case themselves .probably got more as a final settlement

who knows, I was just happy to get rid of the POS picasso and draw a line under it all .
I'm not a fan of buying anything on credit ,however, paying for a bill for services with a credit card, then paying in full the credit card balance at the end of the month ,paid off well in this case.
I had good evidence, photographs ,engineers report, the damaged car etc ,and could have pursued the case via small claims and I expected to win, BUT was happy to let the credit card company factor the debt and deal with it ,because it takes a lot of time/hassle to deal with .
In Mr Varche's case, I'd hope to be refunded the cost of replacement wheel,tyre, hub and wheel nuts and fitting , plus a token gesture (say £50

) and leave it at that.
