Mercedes-Benz S430 Reviews

Really I am not from Washington DC but Bishops Bridge NSW Australia.2325.
Only way I could get to say my piece.
My 2000 S430 is the most comfortable and luxurious car I have been in and I get chauffeured from airport to the Casino every second weekend in all makes of limos, that does not mean I am RICH.
I have difficulties in Australia with support as you can imagine there are comparatively few S430 Mercs on our roads.
I also have problems with the PLASTIC below the drivers seat that needs to be replaced. Where can I get a replacement, I don't mind paying freight from the USA. I may even visit Vegas again to pick it up. Love my Merc. Roger.

Sadly, my family has experienced Mercedes Benz E320 and S430. I enjoyed the E320 way more than the S430. I feel both cars were poorly designed, the cost of repairs closely added up to the cost of purchase. I've owned a Ford and Toyota, and they've spent less time in the shop than the luxury cars. Problems ranged from: suspension and exhaustion hose issues(E320), power steering issues, electronic problems with the trunk and power windows, and the navigation system (S430). Mercedes Benz is just a status symbol, it's not a quality car. It's a joke to own one, but an expensive one at a combined $200,000 or so cost.

I have replaced the plastic that surrounds the bottom of the seats twice because they crack and the compartment under the seat for storage has no support, so it just hangs to the floor. I hear that's chronic. I have had problems with the front end and suspension. My rear window keeps letting down when I crank the car. My engine is ticking loud enough for you to wonder if I have oil or need it changed. The first 8 years were glorious, but I have to car shop, now. I had planned on never giving it up, but lately $3500 within 3 months has changed my mind. This is my third and only Mercedes that I have had this much trouble with.

This is the first MB I've ever owned and its the best car I've owned. I have had several luxury vehicles and am a chauffeur by trade. I have over 250000 miles on it and you would never be able to tell it. Im going to try to get at least 400000 miles same engine/trans.

I have a 2005 MB S 430, Granted it stays in a heated garage and is cleaned all the time.. I have had no problems with this car at all 130,000 miles. Just brakes and tires, reg oil changes. The only part I have replaced is a heater control valve in the cowl area, $175.00. no big deal. The car is adult driven and yes I did buy this car new. Going on a trip this summer and I am planning on replacing the Belt before going.(age)
