2017 Interstate Lounge EXT
No expert here, but for comparison we purchased a 2017 (on 2016 MBZ chassis w/ 4 Capt. chairs) Interstate Lounge EXT with 8,125 miles in late May. It had never spent a night outside, as former owner used it only for business, and occasional football tailgates. We paid $132K in the SF Bay area. Although it checked out well at the dealer, we have since had to replace the vehicle battery, and the radiator fan belts and air filter which we did at the MBZ dealership nearby. Hope this is helpful.....
