07 in my sig, 160k miles. Wouldn't hesitate to drive/haul/tow anywhere any time. Maint, care and particular vehicle issues are the biggest factors and I'm comfortable enough with the above things to trust the truck.
With a good eye on the above an older vehicle CAN be just as reliable as a newer one, but the propensity is still greater for an unforseen issue on something that is 10-20 years old. Like that one dry rotted heater hose that leaves you on the side of the road with no coolant, or a brake wheel cylinder that finally gives up the ghost, or the AC compressor or alternator crappping out. These are all "little" things that can ruin your day that have a higher probability of happening with age.
So with that in mind, now it's a game of what's your tolerance or ability to fix these types of issues (if or when they happen) vs the big $ saved by buying newer?
