Am looking to buy a 1980's SL. I welcome advice on pros and cons of the SL in terms of reliability, level/cost of maintenance, suitability for driving around town, and things to look for when checking out cars for sale. Have been focusing on the 1986 560SL but am open to suggestions. Will use it to drive around town so can give teenage son my suv. Thank you in advance for any advice you can give. - Holly
