Mercedes-Benz S430 Stories
I have major suspension problems and the trunk looks open all the time.I have had to repair the suspention/ air shocks 3 times at $4,500 a whoop! There should have been a recall on the suspension system it is dangerous and costly. I have broken down 3 times with my car sitting on the street like a lower rider, SHAME ON MERCEDES

Crap crap crap. this is the worst car I have ever owned. Every 3-4 months its another trip to repair shop. I think I have funded his new boat. Cranks sensor, SRS error, random noises in front suspension, a/c not working, sun roof error won't auto open/close. The list goes on and on. Never a MB again.
I have owned my 2004 S430 4Matic for about a year and a half. I bought it with 50K miles, this car has had more issues. 4 month's after buying it, it was in the shop for electrical this, pump that,pulley this etc... $5000.00 later. I was pissed and feel that the BMW i owned for 11 years, that was NEVER in the shop except for oil change, tires and alignment is a way better car. If i go high end cars again, I will only go BMW.
I purchased my 2004 S430 last year and I must say that the car has been in the shop more than in my garage. Major suspension problems. Replaced two struts and air pump already. Very sleek car...get tons of compliments. Be ready to spend a fortune even with warranty. Additoinal bells and gadgets that mercedes places on these cars are really not needed..just costs you extra money. Car not recommended for your average nine to fiver!!!
