My God, that was a quick sale. As they say, the cheaper the price, the quicker you get a sale. BTW, in my opinion the correct mudflaps, and if properly fitted, are a most useful accessory. Wheel Arch moulds do set off a car's lines quite nicely, especially the W116 and W126 chassis cars.
When I bought Gleaming Beauty, she had been fitted with wheel Arch moulds. They were probably just a little tatty, and perhaps somewhat on the wide side. I finished up replacing them, plus more sets over the next few years. In the end, there were so many ugly screw holes which basically forced me into replacing the front guards when Michel's Jerry painted the car. It was a good move. Regards.
N.B. One unfavourable aspect relates to the front moulds on a 6.9. If ever one has a levelling issue with the front suspension, wheel arch moulds will take the brunt of the weight of the car, even if wheels are in the straight ahead position.
