My father had one and I swear to you it outlasted it’s lifetime. My father beat the living shit out of it. Never changed the tires, several accidents, 0 maintenance. Built like a tank.
My dad had a shitbox Astro too, thing would not die and he wouldn't get rid of something that still worked. Used to ride around in it on country roads in upstate NY with the side door wide open, stoned to the bone. It felt illegal and dangerous, but cool - literally and figuratively. If you've never ridden around in a van with the sliding door open, out in the country, preferably baked out of your gourd, I recommend it.
