W126 or W140 ?

Well my 86 560 has developed a bad front main trans seal leak (probably been there all along), and now I am seriously thinking about trading up to a 92or up W140. I know of a few for sale from 4k-7k, and am wondering, which model is the best (i.e. most reliable). V8 or 6 cylinder? Pre '96 or Post '96?
All ideas appreciated.
Dave

This topic has been discoussed endlessly on this forum. Do a search and you will find tons of information.

Basically get the lastest production year possible (97-98-99) with the lowest mileage (less than 100k) and with a PERFECT maintenance service record, including new evaporator and everything in working order (including self closing doors/trunk).

Anything besides that is asking for BIG trouble on a W140.

main seal = $1500 maybe, 140 unexpected repairs = $5k easily

think long and hard

Totaly different cars, the W140 drives many times better than the W126.

The best W140 is a super low mileage 1999. Paying top dollar for a perfect example is money well spent.

for myself i would prefer finding a perfect 126. the 140s are too massive and too complicated for me.

and when i drove a 320se (140) it felt pretty much like a 126 to me.

Since I've recently started driving a '92 300SD around for a bit, I see no big difference (mpg gauge is a nice feature). Maybe a wider center console, and more headroom.

I once thought the W140 was massive in comparison to the W126, but they are virtually no wider than the W126 (the American bumpers are bulky even on the sides). I lined my 350SD up with it and took measurements. They sit an inch or two higher though. They have a nice supple ride, and less interior road noise and a tight turning radius. Definitely a solid ride, and not such a big car after all.

They sure don't handle like a near 2.5 ton car. They are very light on their feet, and I have a lot of trouble believing the car weighs 4600 + lbs.

The W126 is a much better looking car, IMHO. But the W140 is not terribly bad looking either.

Not enough of a difference between the two. An S-Class is an S-Class.

Me too. My next MB will probably be a super low mileage 1986-87 420SEL or 300SDL. I love the looks of the W140 however.

Thumbs up

The trans front seal is a common issue with the 722... it's about a $7 and will spend about a day swapping in your driveway or 3-4 hours on a lift @ $80/hr so maybe $350 tops by my numbers.

You can't really compare a 140 to a 126, the suspension is FAR more advanced on the 140...
