Great Great Great service, such a well organised firm. Always got back to me whether it was good or bad news, I hate companies that lie and leave you in the dark. fantastic job. Vehicle drove better that new.

Mr Peterson - Nissan Qashqai - Leeds

Vehicle had been in with two other garages (so called specialists) that couldn't fault the vehicle. Signature said they might need the vehicle for a few days to get the fault to occur. it did once, but knew what the fault would be instantly. Fine job Lads Thank you!! Definitely recommend.

Ray - Maserati - North London

Very impressed with the service. Vehicle came back immaculate, hand washed as well, so no scratches from cheap car washes. Good turn around time considering some parts came from the states.

Mr Spacey - Honda Jazz - Southampton

I found the STL team including Martin and Simon to be very professional and informative. Having just brought a car with what i thought was a noisy wheel bearing they soon diagnosed a rear diff issue. Within 2 days they had the car in, fixed and returned to me. I would recommend STL for their service and expert knowledge which i have found second to non. Many thanks guys.
