For me it has been utilitarian vehicles to fit the scope(s) I choose, able to take them off road into public land.
I do not own darkness, so choose to be able to go there any night year 'round.
Some four cylinder, some six, all used, researched for reliability beforehand, no car payments, winter road worthy.
When road salt finally compromises reliability as first tier telescope transport, then they're a non astro back up, or sold.
This was a slow adjustment into 4WD/AWD from earlier years without.
Getting stuck on winter secondary roads, in what could have had a serious outcome... one astro excursion, one not.
But someone just happened by with a more capable vehicle.
Not a deuce and a half or monster truck, just some more traction and ground clearance wheel base ratio.
