On ebay right now I am selling my 1972 300 SEL 4.5. It has 122, 9xx miles on it. It is my daily driver and I have done much work on it. Brand new handmade SS exhaust, new fuel pump, fuel filter, fuel regulator, fuel modulator, SS fuel lines, New brake pads, new air filter, etc etc. The paint it in good condition, there is some rust around the wheel wells. and some rear bumper damage. The interior leather is perfect; the interior burled walnut dash and wood trim is in very good condition... very minor warping that is barely noticeable if you look hard at it. and its faded. The roof material is also fine and not falling down etc etc. Mechanically this car is very good though it has a small hole in the driver side manifold so the car sounds loud when it runs, but it has a new exhaust system from the manifold back. Email me if you want more details on the car or if you want to know exactly what work i have done on it. Oh the air bags work perfect and stay inflated for 3-5 days after running depending on the weather. It has power windows, vacuum power locks, A/C (still works), power antenna (doesn't go down), power sunroof, has a stereo from a '81 200 series benz i beleve cause the previous owner wanted a tape deck.... thats about it . here is the link to the ebay auction page... if you are interested check it out..
