Sorry, dude, but that doesnt change the fact that MOST (not all) Mercedes are poorly built cars. For bieng so expensive, you think that Mercedes would put some money into upping the quality of the electronics and engine, instead of making a car or SUV for every single niche out there, and even ones you didnt know existed.
You may be rich enough to keep your AMG running for a long time. But most people dont have the funds to just throw money at problems that can and will arise.
Dont get me wrong, Mercedes have nice interiors and exteriors, but you think that they would at least TRY to improve the quality of their products. If you want a high end luxury sedan or suv, get a Lexus. It'll last MUCH longer, and wont be very problematic.
