The Luxus was the high-end LeSabre for '74, and it came standard with a snazzy steering wheel, special hubcaps, and a vinyl notchback seat. The convertible sold for $4,696, about 50 bucks less than the '74 Caprice Classic convertible. Yes, the big Chevy convertible cost more than the big Buick convertible!
This example is in great shape, either a low-miles original car or a good restoration. Given that this is Alameda, I'm betting on the former; you see a lot of original-owner cars of this era on the island.
Once you're done looking at the photos of this car, you can vote for your favorite Alameda convertible. I'm not including homemade convertibles, roofless customs, or vehicles with removable hardtops- just cars with true convertible tops.
