Buick GSX

Q: Greg, what is a 1970 Buick GS coupe worth? I’d love to buy one, and I am checking the ads in collector magazines for one that’s already been restored. — Harry, Detroit

A: Harry, I’ve always had a special place in my heart for Buicks. My grandfather had a black 1948 four-door straight-eight, and as a boy I used to sneak into his garage and sit in that car for hours, dreaming of the day I, too, would become a driver. Along the way, I owned a 1951 two-door Special, which I bought in 1969 for only $300, and a 1983 Park Avenue, which served my family well with 115,000 trouble-free miles.

Buicks also made a strong impression during my high-performance years. Many a Chevelle SS396, Roadrunner or Tri-Power GTO were surprised by the strength and winning ability of the ‘67 to ‘71 Buick Skylark Gran Sport line. These screamers, especially the Stage I and GSX, looked good and ran like the dickens.

As for pricing, a show-quality, fully restored 1970 Buick GSX will run $30,000 plus. Expect to pay $24,500 for the Stage I, $18,500 for the GS 455, and around $15,000 for the GS350. Remember, these are approximate prices.
