Buddy is prepping a 450 Flatbed and a 550 service truck for sale at his shop. They were service trucks bought at auction in Texas. They generally have about 100K on them. I will check specs on the 450. I am not sure if its a 4door.
If you are ever in the Wixom/Walled Lake/Novi area check out Johnny's garage at Pontiac Trail & Beck. Local guy buys service trucks at auction in Texas and brings them up here. He has them detailed, brakes gone thru and puts new tires on them. He parks them at Johnny's. I don't know what is sitting there now. Stock is always changing, trucks usually have less than 100K on them. According to the report I heard on the radio yesterday there will be a lot of Texas repos available.
