It's not just the years, it's the miles, too.
Condition would be a part of the judgement. A beat-to-death Cobra 2000 that was left running 24/7 for 25 years and a clean low-mileage 142 might get me to lean toward the cleaner low-miles radio.
MIght.
The 2000 is a top-of-the-line model, all the bells and whistles.
The 142 is more the half-ton pickup. Still gets you there, but not in the same style and convenience.
