>>> £700 seems rather a lot
Not particularly, Waterboatman. The head gasket went on my Ford Escort six years ago. At the time I was working as a relief delivery driver for a Ford main dealer, taking car parts out to lots of local garages. So, as I went around them, I asked each of them what they'd charge if I'd taken my car to them. The lowest figure I was quoted was £600 + VAT (= £720), with most places quoting at least £800 + VAT (= £960). I eventually got my wonderful local guy to do it for a total figure of just £487 but £700 is definitely very much at the lower end of the figures that independent garages around Suffolk and Essex were quoting six years ago.
Like Kassee's son, I was hoping that the job could be done fairly quickly but the head grinding part of the work had to be outsourced to a specialist firm, meaning that my car was off the road for the better part of a fortnight.
It could well be that the garage Kassee's son is using also outsources head grinding work, with that being the cause of the delay.
