My '19 2LT Z51 Convertible was 75k.
After dealer discount, it was 68k.
Figure if starting price is $60k, the Z51 package is around $5k upgrade. If you decide on 3LT, thats an additional $10k.
It looks like GM has streamlined the vette to keep costs low. Every engine comes with a sump, where with the C7 only the Z51 and up had it. Every car has an automatic.
When I go to C8 site to customize the car, I definitely don't see as many options to choose from that the C7 had. Granted, that could just be due to it being year 1 and their goal is to get as many as them out on the street. I definitely wouldn't expect any discounts on a 2020.
I'm waiting to see what the convertible looks like. I have 13/14 months remaining on my 24 month lease. Don't know yet if I'm gonna keep mine or go with a 2021. I have zero interest in the coupe, cause the only time I drive with the top up i when I'm leaving the car wash.
