So long as you use full synthetic every 5000 miles and premium fuel, the 1997 s500 will be a loyal trusty steed. I love the black on black color combo, 11 Bose speakers and HID headlamps. Also the auto sensing wipers are great. 1997+ have these features stock.. The car is a tank.
The most overengineered MBZ ever built. Love the Black leather, don't get the beige or gray. Even has a parking assist in 1997 ! I love this car. Best driving car I have ever driven. Parts are very $$$ if you buy this used. You can get one for 7K, but make sure it has been taken care of. Mileage is meaningless on this car. Maintenance is most important, and a good mechanic. These cars can go to 1,000,000 miles actually. I think it's in the world record book. The car drives like a sports car. The car is very heavy, so get the S500, not the weaker S430 or S300, there too weak to pull this much weight. And get black interior.
Burlwood dash, keyless entry, vacuum doors/trunk, solid heavy duty feel, sports car like drive in V8 (S500 only), parking assist, electric rear sun visor. Double pane glass.
It's perfection. Maybe make replaceable parts more affordable, but then it wouldn't be a BENZ!
I have owned a few MBZ in my life. I had admired the W140 chasis on the road for many years. The square bold looks, & rock-solid build looked indestructable. New price: $ 100,000 A few points: Steering Wheel: If you can get a wood steering wheel. Hard to find. Interior: Black is the only way to go. Grey / beige don't age as well. Engine: This is a super heavy car. Don't waste your time with a V6. It's like using a wheel barrel to pull the Queen mary. Stick with 97-99. This cars can be had for 7K-8k used, but buyer be aware. Most of the lower priced ones need work of easily 10K - 15K. Get one with service records & an anal owner, that had the work done for you. 10K-15K
Double pane bullet proof glass, 0-60 in 5 seconds. Huge backseat. Vacuum doors / trunk, Insane lumbar support. Square look of car. Solid feel. Unsurpassable build. They don't make'em like this anymore.
Haven't had the car long but have made some extended trips. MPG was a little over 20 on these trips. Performance and comfort are excellent. Still a classic for MBZ styling. With good care should remain a symbol of classic style and quality engineering.
