I found a beautiful red/black interior 560SL, 1984 model, with 91,000 miles on it. The price was right so I said why not. Now I was wondering - the lady who had it for the past 7 years had her husband do all the work, and it runs fine, but I just dont know what is up and coming maintenance-wise. When should I redo the timing chain, I was assuming it would be an upcoming project, since most cars require it around 110-125K. Also, it only has a hardtop, and I was wondering where the best place was to get a soft top for it. Any feedback would be appreciated.
