Chev or Ford?
Definitely do all the service. Brake fluid flush too, coolant, diff fluid. Just do everything.
Both brands will go a LONG time if taken care of. I've owned both.
Watch for tire date codes - and weather cracking/checking.
Somebody local just bought one in this vintage with 26K. Seems they're all over the board.
I have 35K, a lot of redundant service, but I do it myself so no biggie. Just did coolant again for the second time - dexcool.
I keep the trans changed too - cheaper than a new one.
I forgot to look at that hood mechanism last night...
