I don’t know about age being a killer for daily drivers. A local farmer who lived a few blocks away from me passed away not many years ago and was on the road every day with an old car.
He had a 50s GMC pickup and a 65 Chevy Bel Air (bare bones, tan 4 door grannymobile) and not a day went by that he wasn’t out all over the place with that Chevy. In spite of his very advanced age he was a good driver although he seldom reached the speed limit; always loitering 5 or 10 under.
To look at him in those old crates and with the faded overalls which he wore every day one would think that he didn’t have a dime to his name. He was loaded and his one sacrifice to spending was to build a new home not many years before his passing. He paid cash for it and parked inside the double garage of the new home was the GMC and Bel Air.
The only issue I could see with the '88 in question is that it’s an EEC-IV model with the problematic TFI ignition module but that’s an easy fix if ever needed; assuming it hasn’t been done already.
It does have a diagnostic connector for a simple code reader or which can be used with a VOM.
Pulling codes is easy on these once you learn the process and the process is not difficult.
