While an expert staff leads customers through an inventory of new and pre-owned Hyundais outside, Shawnee Mission Hyundai's service department hones in on parts and appearances. Hyundai-certified technicians wield factory-approved tools as they change oil and filters, replace batteries and brake pads, and tackle other auto maintenance and repairs. The shop also lavishes cars with hand washes and detailing packages that target surface imperfections with clay bars and protect exteriors with paint sealant. Drivers can await their rides in one of two lounges stocked with flat-screen televisions, magazines, free WiFi, and complimentary coffee. A play area keeps children from assessing the Blue Book value on their Matchbox cars.
