Be it for standard maintenance or customized performance, Matt REALLY knows his stuff.Quick story - before finding AMG Automotive I was serviced at the stealership; had a CEL going off and they quoted me a $4k+++ repair. After having the car with Matt for 1 day it turned out to be a $200 problem!!! Seriously, if you take your car to a dealership now you should absolutely consider a call to AMG Automotive instead...Since that initial experience, I have had AMG Auto work on my ML63 and CLS55 AMGs for everything from oil changes to S/C upgrades and tuning.*knowledge isnt limited to Merc BTW, tons of experience with american muscle*Be if for the simple stuff or awesome performance modifications - call Matt
