As you paid $86K for yours, assuming it was not a recent year, heavily dealer discounted from MSRP price you paid, and as you seem to not want the ME’s HT convertible option (and you paid either $4,000 or $5,000 for your soft top convertible), start smiling right now.
However, we strongly suspect new options would become available on the C8, such as a roughly $1,500-1,800 front axle lift system, so if you start to check new several options boxes, you could self-select there not being a ME from your self posted “not much over $100K” C8 budget.
I suspect you will have discipline, and not choosing too many new options, and consequently there would be a ME coupe in your garage!
