Skilled workmanship, great customer service, competitive prices, and a good warranty.
I called EuroTech and another equivalent shop in Medina for a quote to replace my clutch and rear differential bushings. Both shops came back with very similar quotes, but EuroTech was a little better in that they actually emailed me a PDF quote with a breakdown. EuroTech got started on my car the day after I dropped it off, and had it done in less than a week (this is pretty good since both jobs are pretty big). EuroTech also provides a 3 year / 36,000 mile warranty on the work, which indicates to me that they will make sure the work gets done correctly. Also, the warranty can be used at any Bosch service center nation wide, which is really good to know.
