I considering purchasing a 420SEL so that I have more room in the back seat when I take clients out versus my current 1990 300E. I'm fine with the more dated look. I also imagine the additional cylinders will help the car's performance with 4-5 adults in the car. I did a search but couldn't find the info even after viewing 8 of the 15 pages of results.

Relative to my current 1990 300E which I have always been very pleased with but need more room, what do I need to know about purchasing the same vintage 420SEL?

Thanks,
AL
