I am looking for a mint, low mile 550 in Red/Tan. If anyone knows of one please let me know.
Good luck with that...They are either re-covered or will need to be with most 550s...Common issue and very expensive to do.
As long as it has been done correctly then it isn't a problem, and you will never be able to tell. And like GS stated above, if it hasn't been done, it will need to be eventually. Thats just part of the 550.
The reason it is mentioned in the ad is because it is a very positive thing. The pickier you are about this kind of thing, the harder it will be to find one and the less likely it will be that anybody wants to help you.
Good luck, I have only been there one time, but I was very impressed with their operation. I hope it works out for you.
