I have a 77 Cutlass Supreme Brougham 4 door. A 4 door is quite a different beast entirely when it comes to what it's worth. It's very hard to judge. Honestly, it is worth what you pay for it. When you sell it, it's worth what someone buys it for.
As a more door, it has less "collectibility, " therefore less $$$.
Trust me, a green 4 door will only bring a select few individuals when you go to sell it. Me personally, I think it is very cool. I love the 390 factor. That will make it more fun to drive for sure!
They always bring good conversations at shows because everyone had one sometime. Yeah, they may have had a 442 or hot Camaro, Chevelle, Mustang, Road Runner, etc., but someone always had the 4 door "family car."
I always get the stories of people having one just like mine, driving one across the country on a trip or vacation, or the car they learned to drive on, or took on the first date, which may or may not have led to the first makeout session in the back seat. Even with my 442 sitting next to it, I always end up talking to people about the Cutlass.
If I were you, I'd buy it, give it some detailing love, and drive it!
My 4 door also happens to be green, and I thought about selling her when I first picked her up.
That was 22 years ago.
