I see your point, I did just as you are posting, I went and bought a brand new E350 sport coupe just a few weeks ago but I only lasted 265 miles in it, It was just not a patch on the C63507 in any way, nice car, but not for me :fail saying that, now my 800 mile old C63507 is up for sale due to a " issue " with Merc Uk over my car having the wrong ( std c63 18s fitted ) wheels fitted and Merc uks ****ty attitude, Its a R8 V10 for me in the spring and that will be the last merc I buy.
Don't know the detail but you're binning a car because it had the wrong wheels on it? Did they get the original order wrong i.e it should have been 19s? If you ordered something and didn't get it then "Sale of Goods" could be brought up maybe?
If you can afford an R8 V10 you could get a decent set of aftermarket wheels for the C63
