Thought I finally found a local, loyal, dedicated, honest dealer with integrity. It was a mirage. In September 2017 we bought a CPO 2013 GL450. Wrote a big check.Nice car, but from day 1 the suspension clunked and creaked going over speed bumps at parking lot speed.. I took it in for this complaint on 2 occasions, only to hear "Could not replicate" and "Its normal" from the service writer.(I have a GLS63 in Seattle that doesn't do this.) I decided to trade in this GL450 SUV I bought from MBZ PS 18 months earlier and adding only 7000 miles. By now the warranties have all expired. The trade in value they offered was ridiculously low, (25% below what KBB claimed) and their retail price on the newer GL550 SUV was astronomical.( Compared to KBB comps) So I had them service it. They charged me $3800 for rear shocks that have been bad "for some time" I asked about the complaint of suspension noise that I brought up during the warranty period. He shrugged it off. I wrote another big check. Drove the GL 4 miles back to our vacation condo, parked it and flew back to Seattle. 4 months later we came back to our desert home only to find the suspension was flat again. I limped it back to this dealer, waited 2 days for an opening in their calendar. Now they want $4500 to fix the front suspension. Now I'm pissed. The service department doesn't care to review my service history and earlier complaints of same. I left a message for Gary Whittaker, the owner, and no reply. Fed up, I took my car back, drove it to a local independent MB service shop, International Motors on Ramon Rd. Sean diagnosed the same issue, and fixed it for $2900. I got it back next day ( He actually got the OE struts wholesale from MBZ of PS) Conclusion: I feel that the MBZ Service department wrongly diagnosed a service issue with the suspension while the car was under warranty. Their negligence ended up costing me well over $7500. They were not willing to do anything about it. I know this because I received a text survey after I took my car back which I replied "Completely Disappointed" . No one followed up.
