Finally won this car at 3334324, PR 85.3, 22/28 upgrades. That's 420 - 100 = 320 GC spent for an 800 GC car which does NOT get 20% showcase discount, as such I think it was a good deal even at these upgrades. And it is the one that is slightly cheaper to upgrade to get 100% on Group C 1991 should you even want to waste a lot of gold but still save some, so there's that as well.

7.4 and 8.2 were the toughest nuts to crack, but strangely I didn't upgrade on day 8 at all, since I had upgraded to this level to pass 7.4.
