I have 2012 Citation Sprinter 24 sa. I haven't had it long but the previous owner took excellent notes. With 50k mile the only issue were routine oil, filters and tires. This was one of the reasons I bought. I just upgraded the charger and the battery isolator. With an MB there is an A service and B service that the previous owner took care of every 15 k miles, there not cheap but look like will keep the chassis in good shape for the long haul.
