2005 Mercedes-Benz M-Class ML350 AWD 4dr SUV (3.7L 6cyl 5A)
This was my first MB purchase, and I bought it for the "reliability" and craftsmanship - HA! At 26K, needed to replace all 4 tires (get rid of Dunlop!), had leaking rear differential and the low-range light kept flashing. At 52k, entire front end had to be rebuilt (just off warranty, thank you very much), needed new front brake rotors and brake pads all around, front headlight "leaking". At 72K, had to replace radiator (cracked extrusion joint), and rear differential again had to be fixed. I can't wait to get rid of this crappy car.
Lots of interior room.
Try improving the overall quality of this "wanna-be" luxury SUV - otherwise, stop making this model.
