Hi all long term lurker in the forum some great content and research available here. Got to MSL after reading up in this forum I booked my c63 in for headers and a map. Went up from Kent. Everything said in here is correct msl Birmingham is the place to go for any work. Acid walked me through the whole process, showed me the parts, all the lads were into the cars you could tell it was a good working environment. This guy deserves all the success he gets as the customer experience was excellent. Lots of AMGs in that day another w204 c63, A45s, C63s It was a breath of fresh air for me all be it a long day. The car is transformed into another level of sound and power. If you are in any doubt I wouldn’t hesitate as they are top of the game in my view. Another endorsement from a happy customer!
