the issue isn't make, it's the age and depreciation - how much would you pay for a 1987 car? An older bike will have some value only if it's a real classic - like a 7-eleven team bike, etc.
The problem with comparison to a car is that cars have improved a lot in the past 20+ years. They have air bags, anti-lock brakes, satellite radio, get better gas mileage (generally), etc. Also a 20 year old car maybe nearing the end of it's life.
A 20 year old bike that's not been abused (particularly if it's been ridden very little) is still completely useful. The technology has not changed that much, and although there are improvements (integrated levers, more rear cogs, double-pivot brakes, lighter materials) bikes works exactly the same as it did 20, 30 or 50 years ago. I often commute on a 30 year old bike, and I see cruisers from the 50's and 60's biking past my house every day. There's nothing wrong with old bikes.
The good thing about buying used bikes is that you can get a really good deal on a good bike. The bad news, in this case, is that the bike is too big, so was a bad deal at any price.
Given that prices are determined by demand (instead of usefulness), $220 was a bit high for this bike. But there are plenty of bikes that age or older that I'd love to find for that price.
