 First off - I loved the car - very smooth, elegant, pretty, powerful, roomy, quite  - all the things you expect in a MB. So I bought my 2007 MB GL 450 in Dec 2015 (8 years old)  with about 160k miles on it, knowing I would have “some” issues, but hoping the legendary MB quality would serve me well in the end. The car was $13k so it seemed like it could work out even if I had some reasonable repairs. I have owned the car for 8 months ( about 12k miles) and have put almost $10k in repairs - all local mb repair shop or  NON MB DEALER costs! First off - I called 3 dealers - all told me basically to pound salt! None of them would even TAKE ME as a customer - saying that since I was not the original owner, they would not service a MB that old! HUH - yep, I was told by 3 dealers that they wouldn't service my 8 year old MB!!!! "People that buy older cars like yours typical don't invest in maintaining them the way they need to in order to maintain to the manufacturer specifications "  - MB basically called me a cheap ass who wasn't going to take care of my car so they were not going to even talk to me.....anyway moving on.... First month - rear air shock $450, second month other rear air shock $450, Third month - intake manifold $2,200 (plus 6 weeks waiting on the part), Fifth month - vacuum hose-$100, fuel cap - $30, evap canister $850, Airshock Compressor - $1,250, sixth month - steering rack $2,200, seventh month - both front airshocks $1,200, interior trim dash - $250 (broken tray), interior trim rear seats $500 (rear seat would not lock)   - thats $9,480 in repairs. Maintenance wise - 2 oil changes $220, 1 set of tires $820, 1 service b - $300 totalling $1,340. I also bought 2 missing headrests ($600) and the bluetooth phone unit ($300) when I first got it. So far, after 8 months, I have put $11,740 into my $13k car. BIGGEST MISTAKE OF MY LIFE!!!!
