I've used them also for car tyres, very quick service and very handy as they will come to you to fit them (and the cheapest around at the time!). The only negatives were that the fitter damaged my alloy wheels when fitting the tyres (chipped the laquer and paint in a couple of places) but this could happen at any tyre fitters, also the wheels were balanced using a machine in the van and these machines do not balance car wheels properly, they are designed for narrow motorbike wheels and only balance in one plane so I would suggest getting the balancing checked elsewhere if possible.
