My buy was awful, but Costco continues to work with them and the next 2 were better...but...Their service department is the WORST. Not only the workmanship, but documentation, and the follow-up. They simply don’t care. If you go thru Costco, don’t use the Larson service department. I’m not sure, but maybe, since Larson owns all makes of car dealerships, service may not be important to them. As for me, I choose never to have their incompetent, bumbling, technicians ever perform another service for me...or, in some cases, say something is normal that is clearly in need of repair.
