2007 Mercedes-Benz S-Class S550 4dr Sedan (5.5L 8cyl 7A)
The S550 is a great looking vehicle. However, my vehicle has been in the repair facility three times in less than two months of ownership and it's still not fixed. The vehicle is on its third set of tires since I purchased it in June. It is also next to impossible to put fuel in the vehicle at a rate above a trickle.
