Found these guys by chance on the internet as I had a gearbox problem on my CLK320. A new part was £580 from a very disinterested Merc dealer and would take weeks to arrive. Second hand parts were around £100, but were they any better than what I had? ECU testing had a super fast turn around and even collected the part from my house. Hard to think it could have been any easier. Text messages to update me all the way as well as a couple of phone calls. 3 days later the Merc was back to brand new and all for £235. Well worth it! Genuinely impressed with these guys and will look to use them again. Not often you find a company this good, keep up the great service guys and thank you for fixing my old Benz!
