a mate of mine left a bmw with them to valet the interior(leather).
they cleaned it and when he collected it it looked really clean. a few days later the leather went all funny and looked proper fucked,they had ruined it but wouldnt say what they had used.
the kosovan owner offered to replace the interior so he left it with them-came back and they had put a set of grey cloth seats in a car that had beige leather......my mate went mad and the guy just shrugged his shoulders and began talking foreign.never got it completely sorted out and sold the car with the ruined leather back in through auction.
i would never use any of them,in fact immigration raided all the ones in warrington this week and some seem to have shut now.
