Not a simple answer in my opinion so had to “spoil the ballot”.
2014 had an inaugural edition c7 corvette with OEM wheels (i have a brand new delivery take-off set of these wheels)
2016 added pilot features like Carplay and front nose cameras. (so I bought my 1st corvette)
2017 had a one-year colour (so I bought a spare c7 - kinda sorta)
2019 had the most desirable but impossible to get at MSRP ZR1 option that later became a
allocation issue (tried to get one with my name at dealerships across the country but nothing came through)
Best thing that GM left behind going forward from the c7 was the buyer’s choice of M6 or A8.
no doubt more to state but enuf for the post other than yes, a couple of c7 manufacturer issues that were easily remedied (at a out-of-warranty cost) but still no real best c7 year in my opinion.
