He could start out by taking new photos. This time, without snow. After all, compared to the other Skylark for sale, this one is afflicted by 4 doors and the rough-running 6-banger.
Car looks very similar to my very first 'company car', which was a '75 or '76 Buick Apollo 4-door. Similar green, too(Until '77, the 4-doors had the 'Apollo' name and the 2-doors used the 'Skylark' name).
It also looks much like my old 1980 Malibu 229 V-6 smooth running and peppy, but with too many doors on this one. By the way it usually snows eleven months out of the year in Janesville, Wisconsin.
Wonder what was optional in the half-empty instrument panel. A clock and what else? https://milwaukee.craigslist.org/cto/d/1978-buick-skylark-sedan/6214727469.html
I wonder why he's got Mazda floor mats, what's he filling up with that funnel and which seats he plans on covering. What does he want for the car?
