Depends. If it is a collector's item, yes. I have friends with '57 Chevy Trucks, run better than some 20 year olds old there.
If you want a daily driver. weigh any repairs you've had to make in past year v. monthly payments on something newer.
A bunch off strangers on the 'net can't make that decision for you.
But, for myself. my newest vehicle is 12, oldest is 38. Still, the old Chevy only really needs a rear mains seal (very hard to replace.) I want to do a complete job while in there, it's my choice that I'd rather do what she needs so I can sell her with no misrepresentations.
