The guys at MSL genuinely go one step beyond what you often find at garages. And this is why I will continue to come back, time after time.

I think it goes without saying that when you work with people that share a passion it’s a joy to be a customer. They take pride in what they do everyday and it shows.

Plus… if you’re really nice, they may even feed you.

Visited this garage for brake disc and pad replacements on my E Class. Staff were professional and accommodating, even offered a drink upon arrival. Technician kept me informed every step of the way. The prices here are very competitive, whilst they still provide outstanding service! After the job was done, I was presented with a Mercedes digital service report. I will definitely go back and highly recommend MSL Performance!
