    I bought this car with 123,000 miles, within 20,000 miles I had to replace the rear axle's and the had to have the rear end cleaned $1,ooo.oo . I travel a lot so I thought I should be good!? no, I now have 280,000 miles with in 3 years, the rear axles and read end have been replaced 3 times and I have to do it again and this will make 4. the front shocks (bad problem) removed and replaced, heater repaired 2 times..... I love the car but what the heck, they need to do better than this. All of the repairs are way to expensive and the makers should give my money back so I can get a car that is worth driving long distance
