I sent my Machine Mart low level alloy car jack into my local shop for repair to the cylinder and piston. They charged me £24 to send it to their repair centre for "assessment", where they kept it for four weeks before phoning me to say that the repair would cost £135 - whilst they could sell me a brand new matching model for £115. I declined. This seems something of a sales exercise rather than carrying out repairs - at least in my case. Very disappointed. I plan to retrieve it, buy the parts and do it myself - since they can repair it they obviously have the necessary parts. Is their behaviour over repairs commonplace?
