Thanks for the response, but indulge me with one follow-up inquiry please. Not knowing for sure what advancements were made between the 1987 420SEL and the 1989 420SEL, I would like to ask you educated opinion. The two front runners for my purchasing dollars are an 87 420SEL with 76,000 miles and an 89 420SEL with 114,000 miles. Your last response makes me feel that the latter may be the best choice. My instincts tell me the former would be best. Please help enlighten me as to which you would choose and why?
