I've owned this for 12 years. Dressed as a Stage 1 with custom black and red painted pin stripes. Fremont built Silver Mist (original color) with black vinyl top and interior. 455 with turbo 400. Bucket seats, AC, period correct aftermarket cruise control (that works), console shift, map light (that works), aftermarket gauges. Added in 2010 after I bought it, new AC system, posi-traction with 3:42 gears, new drive shaft, 15 inch Buick wheels, stock style disc brake conversion, original style radiator, all new suspension, restored under hood to pristine condition, and much more. If you are truly interested I will email you a copy of the invoice for the work performed after I bought it. Included are many parts: new fuel tank in the box, aftermarket aluminum radiator in the box, new wind laces, 3 Stage 1 fuel pumps, new unused Stage 1 solid fuel line, NOS in the box right side rear tail lamp lens for GS plus a few more used, new extra v-belts, windshield wiper blades, several new oil filters, extra black air filter lid looks brand new, various decals, foam for cold air induction, two 14 inch Buick wheels with tires, and there is much more I can list for an interested buyer. AC needs recharging, needs passenger side rear view mirror. $32,000. Very similar to the blue GS that sold at Indy Mecum 2021 for $33,000. https://www.mecum.com/lots/SC0521-459306/1969-buick-gs-stage-1/
I agree, great looking GS. My '69 is envious. And the price seems very reasonable for basically a near-showroom-looking car.
Price drop to $28,000. SOme parts listed in the original post are no longer available. I'm including a brand-new car cover in the rice.
