Buick‘s duce and a quarter is what car guys called the Electra 225. My best friend’s dad owned several of these. They were big with lots of power, they were, well, a Buick. The Electra was a full-size premium automobile built by the Buick division of General Motors. The Electra name (in various manners) was used by Buick between 1959 and 1990. It was a big car and with a 401 cu in (6.6 L) V8 had more than enough power to move it around. It used the C body platform which is shared with Cadillac and Oldsmobile. One in decent condition can start at 20K. I saw one in super great shape on Hemmings.com which was going for 60K.
The promo models can fetch a hunk of change. I found this one on WheatsNestalga.com going for $600. Keep in mind that since it’s a convertible, it can easily suffer cracks in the window posts and the steering wheel. This one is intact. Joe rates it an 8-9 on his 10 scale. On this one the boot and dashboard have light yellowing. Sure $600 is a significant investment on a promo model car but just like the real cars, the better shape it is in, the higher the price. If I owned this, it would go right into my case and only taken out, by me, to share with some of my friends.
