For 1955, you’ll be looking at 17 Tri-Five variants. The most popular 1955 Chevy model was the four-door Bel Air—Chevy manufactured about 366,000 of these, so it will likely be the easiest (though certainly not the cheapest) for you to find. The four-door 210 is your next go-to with just over 340,000 in production.
Since you’re looking at a model to fix up, you’ll likely be able to find one that’s fairly affordable—especially if you stick with the more popular models. Remember, we said fairly affordable—even a trashed 1955 Bel Air will likely set you back several thousand. If you’re looking for that rare-bird Nomad, plan to drop at least $60k.
