I faced the same dilemma recently. Keep the ‘05 Z71 or buy a 2019 like the wife wanted (for me)? I wanted to drive the ‘05 as long as it would run but she wanted a new one with all the safety features ‘cause we’re in our late 60s and might need them. She found a super deal on a 2019 Z71 ($10k discount) so we bought it. I kept the ‘05 for running around, hunting, carrying bags of mulch, etc. and use the new one for road trips. I drive them both daily. The new one is really nice and has a great ride, but the sheet metal is definitely much thinner. I ceramic coated the new one.
