hmmm Nothing in the description about the woodie that used to be on it, judging by the trim for it. Or, why it's all primered now, and what's underneath it. BUT, for a Grand, say hey...
Being a Sport Suburban, the wood was definitely on this car. I have a feeling it is sun damage that dried the Dy-Noc out. The body looks solid, and the stance is about right. Given a decent once over, this could be a good, driver quality, car to have in the garage for a very reasonable amount of money.
