Body appears excellent. Engine has new turbo. Has new tires and brakes. Current owner is car salesman and has owned car four years. Doesn't have records on car earlier, but car resided in Midwest. Needs seats recovered and headliner. Appears to have good power and run smooth on the road, but does idle roughly when in park. Will take to mechanic to get it checked out - any specific things to look for? Mileage concerns me, not having the maintenance history. Thanks in advance.
