The average car is 12 years old. Car makers start to drop support (making/stocking parts) when the car is about 10 years old.

I haven't had any issues with getting parts for my 2008 Sienna, or parts for my 2007 Honda Metropolitan scooter. But the Sienna uses the 2GR-FE though, which only recently stopped production a few years ago, and the scooter is based on the still-currently produced Ruckus 🤔... Still.

Come back and talk to me about that car when is is 25 years old and tell me how it is.

No need - I have two 46 year-old vehicles: a 1980 Honda XR500 motorcycle from 08/79, and a 1980 Mercedes 240D from 12/79. The motorcycle is currently torn apart in the garage, undergoing a full restoration. Believe me dude, I know aaaaaaall about the frustrations of long-discontinued parts 😂😂

I have a 26 year old truck, the bed has holes, the frame is showing signs of rot - I’m trying to decide if it is worth trying to rebuild the transmission, my mechanic isn’t intersted in part because they are not sure if they can find the parts - they will be more than $1000 in labor in before they know wihch bearing it has and thus can check if it can be had.

Man I feel that so hard with the Mercedes. Poor thing has cancer and I'm not sure if it's possible to save in its current condition. It's got almost half a million miles, but goddamn it drives so, so nice... I think it needs a clutch though. Luckily, since W123 cars are sought-after classics at this point, there are still options, but it's gonna be a hell of a process if I decide to attempt a restoration. My dad (with help from me and my siblings, friends, and neighbors) somehow managed to save a pretty rusty 1963 VW Beetle almost 20 years ago, was about a 5 year process. That car recently went to a collector... I'm mad about it, but only in the "goddammit I wanted to inherit it" kinda way 😅
