Cars We Remember: Buick GS lover wants information

Q: Greg, what are 1966 to 1970 Buick GS coupes worth? I’d love to buy one. I want to buy one that’s either already been restored or in good driving condition. I see them on the TV auction shows, but those are priced too high for my wallet. Can you give me some advice? Steve L., Clarks Summit, Pennsylvania.

A: Steve, I’ve mentioned in my columns before that there has always been a special place in my heart for Buick brand automobiles. As the first official make sold by General Motors way back when, my love affair started in my grandfather’s garage, where there sat a black 1948 Buick Special, four-door straight-eight with a manual transmission. Of course, I utilized his car as my playroom from 1952 (when I was three) to 1958, when we packed up and moved away. My grandfather then made a U-turn from his love of Buicks, and purchased a brand new, blue 1962 Ford Falcon. As for me, I owned a 1951 two-door Special that I bought in 1969 for only $300 and a 1983 all-white Park Avenue, which I bought used and drove until it had 115,000 trouble free miles on it.

As for Buick when it comes to muscle cars and specifically the GS models you seek information on, these cars made some strong impressions on me during my high performance years. Many a Chevelle SS396, Plymouth Roadrunner, Dodge Super Bee or Pontiac GTO got a good look at the rear quarters of many a Buick GS, especially from the years 1967 to 1971. These Gran Sports, and especially the Buick Stage I and GSX models, not only looked good, they ran like the dickens. In 1969, my buddy’s 400-inch Stage I model was running sub 13-second quarter miles regularly, and all we did was add a set of headers (an additional 20 horses) and I let him use my 3-barrel 950 cfm Holley carb, which we needed an adapter to work on his aluminum intake. His rear end was a 4.33 posi, and he needed some good M&H Racemaster slicks to hook up the horsepower. I think he ran a best of 12.85 at about 108 of memory serves me correct.

As for current pricing, the nicer the car, the more you’ll pay. A fully restored 1970 Buick GSX 455 Stage I will run $75,000 and up to over $100,000, so this one is probably out of your reach, However, I’d browse the Auto Roundup and Hemmings Motor News publications first as Buick GS models, including the GS350 and GS400, from 1965 to 1970 in driver quality can be parked in your driveway for $10,000 to $20,000. I checked the eBay offerings, and there are many nice ones to choose from, some numbers matching others not. But overall, if you buy a muscle car era Buick GS, you’ll attract a lot of attention at the car shows.

Remember that price guides are just that and many times don’t really do justice to the current market as the buyer and seller determine what a car is worth. Good luck, and if you buy one, please send us a photo! By the way, if you hit the lottery, the 1970 GSX is the best of the bunch. It could outrun a Hemi Roadrunner if both were in factory trim.
