Good service, very friendly and made everything easy… will recommend.
I had a problem with my car that Serg went away and did a lot of research on before he committed to anything. Unfortunately he couldn’t help me with my specific problem this time but he took the time to look into the issues first and did not charge me for a call out on something that he could not fix. I have had a few calls since to see if I have managed to get the problems sorted which shows that he takes pride in his work and genuinely cares.
Serg was polite & kept me informed with what he was doing. Price was what he told me earlier. Will use again.
Excellent work and very helpful.
