I looked at and test drove just about all the different post 1986 w126ers before I finally bought the Mercedes I have now.

I like the look of the short wheelbase sedan, I think it is sexy compared to the other LWB SEL models, which are more stately and formal looking..

They have a LOT of pep for city driving, maybe they have a good rear axle ratio or something. They are highly satisfactory for city and everyday driving

Once you are cruising at 65-75 mph they feel just fine. The only drawback I found with them, was the lack of power for high speed passing and kickdown at 45-60 mph, they were much slower than the 420 and 560. In sum: Generally nimble for city driving, and leisurely on the highway but a good solid cruiser when up to speed. They will be more economical on gas than a V8 but gas mileage should not be a prime motivating factor in selecting a W126, these cars are heavy, solid, durable, safe, long lasting LUXURY models, not econoboxes.

The 6 cylinder engine is a VERY excellent motor. VERY long lasting if well taken care of. Give them a long and thorough look before passing on one.
