Says it's a 1 owner car........... https://inlandempire.craigslist.org/cto/d/gardner-1967-buick-elc-225/7407513451.html
Can't say much for the seat covers, but it looks like it's fairly well kept. It has A/C, cruise control, P windows, not bad...
Who knows what size it really is, it's still wearing the 430 valve covers.......... maybe just an ego boost for him. Bigger is better.............right?
Yeah, they might have put it on to fit a later carb or induction system, who knows, the aircleaner is definitely post 1970. The original was a bigger more bulky affair. And yes, it looks like the 430 valve covers are still there, so who knows. A serious collector would likely run the numbers to see what was in there before he bought it anyway.
