Unlike most of nameplates out there, Buick Estate was envisioned as a station wagon from the get-go. And it remained a wagon throughout its long and storied career. 1970 B-body Buick Estate with 370 ponies prancing out of 455ci V8 won’t cost you more than $7,500 on average. Not bad for top level luxury Buick wagon coated in wood grain. Moreover, it’s the youngest car on the list – three or so years shy of its golden anniversary.
