Wouldn’t surprise me, though unlike apparel there should come a definite sense that obsolete technology becomes really useless really fast these days, as opposed to merely unfashionable. I sense a certain degree of retail predation here.
I own a 1970 Mercury Cougar, which I purchased in 1994. At that time, cars newer than the 1965 model year needed to pass a smog test, which required meeting emissions levels appropriate for the vehicle’s model year. The first time I took it to get smogged, the technician attempted to sell me a kit that he claimed was required for vehicles of my car’s vintage. The kit consisted of two rubber vacuum plugs (with which to disconnect the distributor’s vacuum advance) and a sticker that went on the distributor that described why the plugs were there and that nobody should remove them. And this kit was, ahem, $69 in addition to the cost of the smog check and certificate. I laughed in the dude’s face. He was trying to sell me something that was mandated in California back in, like, 1976 when the state was grabbing at any straw to counteract the smog belched forth by the gas-guzzling V8 engines and non-catalyst dual exhaust systems of the late 1960s. Nailing down the ignition timing must have struck some legislator as a decent half-assed measure to slow the cars down, but I think the requirement to use those kits had been abolished before I was in high school. I have no doubt the guy kept a couple in his shop to foist on unsuspecting schmucks with late-60s to early-70s cars. I went elsewhere to smog my car and passed with flying colors.
A year or so later the smog check requirement cutoff date was moved to 1973, and to celebrate I got meself these license plates:
Last year I tired of the joke (and the added yearly expense of personalized plates), so now I just have normal random plates on the car.
