Possibly a fuel pump away from a beater: https://missoula.craigslist.org/cto/d/1979-buick-rivera/6762741394.html
That color combo is one of the rarer and the most beautiful of the Riv combo's. A friend of mine owned this example with 21K, never driven out of the garage in the winter and never rained on, I look back and kick myself for not buying it when it was sold. It was a checklist car down to leather and moonroof
Instead of "in it a rear wheel drive", I think he meant "enit a rear wheel drive?", which if you're a Native American, makes sense......His phone probably didn't understand his accent or slang term: https://www.urbandictionary.com/define.php?term=enit I'm Native, and my 'cuzzins' use enit for everything hahaha..."Let's get some milk." "Aw, Enit!"
I was just joking there in my reply, just so you know . I mean, everything I said is true haha, but I don't think that's what the guy said. I agree with you and think he probably does think it's rear drive and who knows what it has under the hood.
