On the GTP account, I used the Alfa Romeo 4C Gr.3 on a 1-stop strategy at Sardegna. The 4-star marathon roulette gave me a Nissan Silvia touring car, which, against my better judgement, I put one of my remaining GT-R NISMO engines in as I already had 4 swapped copies of the other three cars that can take that engine as a swap.
On the Plus account, I used the Porsche 911 RSR on a 6-5-4 two-tire-stop strategy at Sardegna. I probably could have gone with a 1-tire stop and won by a bit more than the 2.7 seconds that I did.
The 4-star Wheel of Despair gave carbon ceramic brakes for the GT by Citroen Road Car. As I won't hit 20,000,000 Cr. again before both the Mercedes W194 and the Ferrari 250 GTO sell out, and the next 20,000,000-Cr. car is a couple months away, I bought the 1966 Shelby Cobra 427. I should mention that, when I bought the elderly Alfa yesterday, the replacement value of my Plus garage finally exceeded the cost of the then-29 cars left to buy from Hagerty's. 28 cars to go, 240,650,000 Cr. to spend.
