1978 Chevrolet Suburban w/ Silverado trim

This one owner burb was found in Texas. Having set under a carport since the early 90's, it needed some tlc. We bought it with "The perfect shop truck" in mind. As most projects go, it snow balled into what you see now. The burb was rust free and in running/ driving condition but we wanted the ability to pull a trailer and blow the doors off a mustang if we had to. We have enjoyed the truck and driven it to many shows locally and out of town. It drives better than new, plenty of power, tows great, and does it in style. And for those that want more, it is capable of over 1000hp with a few more upgrades. We can help make that happen if needed.
