Just bought a 1982 380SL need advice

[docpk]

I just bought a 1982 380SL with 84K miles, great body, no rust. Had a mechanic look at the car and said that it had a single timing chain. His advice was to sell the car as soon as possible due to the single timing chain and the expense to convert to a double chain ($5-6k). He said the car is a ticking time bomb. Should I sell?
