mate of my is a mechanic at an mb delaer, or was until he went out on his own. he reckons you need to have a good look around the car and check the bits and pieces. american built apparently, so not as high qulaity as one might reasonably expect from the three pointed star.
trim can fall off. engine very solid in believe. i would go for the biggest alloys i could with chunky wheels for that 'jurassic park' look. (lol, by the way).
also, black hide if possible, beige can look odd in a car imho.
