 The Mercedes R350 is the worst car ever, visibility is poor but the car is very stable driving at high speeds.I purchased an extended warranty thinking that I was going to keep the car but I am rushing to get rid of it.The car only has 45,000 miles but have replaced the battery three times due to a faulty computer, and front shock @ 20,000 miles and the other front shock @ 40,000 miles.Each shock is $1,300 dollars, no mechanic want to touch it.
