Without pics and more information it is hard to give you an accurate price. But I will take a stab at it. Since it is complete and has new glass (that's worth about $600) It has all four seats (that is worth about a $1000) No rust (that's a miracle) Running engine (that's an unknown on condition) Brakes are an unknown, transmission is an unknown, tires are an unknown, interior is an unknown, title and registration is an unknown. Without having any of the unknown s answered I would say $2500-3500. If the unknowns are answered in a positive way $5000 - 7500 I hope that helps and welcome to the Burb section, I have both Chevy's and GMC suburbans. Go to Oldgmctrucks.com for another great site predominantly GMC's. There is a wealth of information on the 47-55 GMC's and Suburbans.
