My initial experience was attempting to obtain quotes on a Sprinter transmission replacement, and after 3 separate calls to follow up, still never received one from these guys. Certified Transmission of Olathe rocks, so if you need anything Sprinter transmission, call up Andrew. The second time was dropping off my Sprinter for oil and fuel filter change, which both were done just fine without issues. A few things that were not fine, is they seemed unsure on how much a Sprinter oil and fuel filter service would cost, as I received different quotes that kept increasing. Final bill topped $500 for oil and fuel filter change, comparable to the Mercedes dealer. I was also charged for 2 different oil filters (different prices?), which I did not catch until after I got home. They did offer to credit my next visit ☹, which probably won’t happen. Other potential issues that I will not go into detail about, are mis-diagnosing the source of an oil leak (verified by 2 different shops) and choosing to remove the rear disc caliper to re-route a rubbing cable, rather than drop the rear shock by simply removing one-bolt. I am always looking for great Sprinter diesel mechanic alternatives to the dealer, but I think I will continue the search.
