1999 Mercedes-Benz S320 Reviews

Very comfortable car seats and ride for any distance.
Only problem I had is the dealer not having good mechanics to evaluate basic repairs. I am trying other mechanics though the dealer is walking distance....
I love this car ride. I would like to give it a new paint and take off any surface rust and keep it for ever...great 6 cyl. engine...great seats....runs on SUPER...

really good cars,just replace wear items and it won't let you dow.Want to beat 500s,its easy with a NOS Sniper nitrous 125 wet shot kit. My track times sor far 10.64@ 96 mpg.

My 1999 S320 is not as stylish as my W109 3.5. My S320 has electrical, airconditioning and drive train issues. Its simply becoming a pain in the neck. I wish Mercedes Benz can build an S class just like the W108/W109 and install a more efficient 8 cylinder engine. Nothing can be better than a W109 S class Mercedes Benz!

Best car ever. Perfect for everything and everyone loves it.
