2006 Automatic I am offering a 2006 GMC Superman, six-lug, double. Second owner for 15 years. Mileage is 302 as shown in the pictures. The car is like new. Body and engine are like new and available for inspection. All its glass has original factory seals. I just had it inspected yesterday and renewed. The car is used with care and is kept in a garage and only comes out for travel. Contact by phone due to infrequent access to the site.
