"Vintage" items on the Facebook marketplace. The word vintage is usually synonymous with something of high quality from the past, now it's code for "this old piece of shit I'm hoping to over charge you for".
I see this in pretty much every hobby I participate in. Old stuff, mostly garbage, being labelled with a "vintage" tag in the title with a ridiculous cost associated with it. This is a big problem with the RC car resale market right now. The thing is, a lot of platforms, mechanically, are very much the same as they were a decade ago. There are vehicles from 2004 that are still being made today, just with modern and more powerful electronics. So often I'll see used vehicles for sale, and the seller is trying to sell them with NiCAD or NiMH batteries, ancient controllers that require you to manually swap out chips to change frequencies, motors that haven't spun in a decade, and chargers that take 5 hours to charge a pack, assuming they don't burn your house down in the process. The vehicles are actually less desirable with these systems in them because literally no one wants them anymore. There's no "cool" aspect to using a 20 year old battery like there is an old engine. It's just an under-powered, dangerous, buzz kill. I'll pay more for a model in rolling chassis form with no electronics because that's less work for me in the long run. So many people say "yeah, but it comes with the batteries and a controller" and don't seem to understand how outdated and unusable the old equipment is. Modern ESCs can't even run off the old battery packs. It'd be like someone trying to sell you a 15 year old cellphone with a charger that doesn't connect to modern towers, but asking $175 for it because it's "vintage".
Not really sure where I'm going with that, but it's been pissing me off lately.
