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.
If you want a luxurious sedan. This is it. rides smooth extra quiet with its double pane glass (looks like bulletproof glass). but of course when you buy luxury, guess what maintenance is luxury too. :)
