Yeah with these Group C cars all coming in a fair bit under my estimates the total is going to be a bit less than my 433M estimate, unless any of the remaining ones are way over my estimates. These were my original estimates:
Chevrolet | Camaro Z28 | 1969 | 35,000 |
Chevrolet | Corvette Stingray Concept | 1959 | 75,000 |
Dodge | Challenger R/T | 1970 | 90,000 |
Ferrari | 330 P4 | 1967 | 8,000,000 |
Jaguar | D-Type | 1954 | 12,000,000 |
Lamborghini | Countach LP400 | 1974 | 750,000 |
McLaren | F1 GTR Kokusai Kaihatsu | 1995 | 7,000,000 |
Nissan | Skyline R34 GT-R GT500 | 1999 | 1,500,000 |
Plymouth | Superbird | 1970 | 220,000 |
Porsche | 962 C | 1988 | 3,000,000 |
Porsche | Spyder Type 550/1500 RS | 1955 | 4,500,000 |
Based on the others the 962C will probably be 2 or 2.5, D-Type could be more though I guess. It depends whether they value it generally, or against the exact model in game.
The real one that sold for $21M in 2016 was the 1955 #4 that won Le Mans in 1956, the model in GT7 is the 1954 #12 which was driven by Stirling Moss in 1954 but DNF'd, so unlikely be as valuable.
Sotherbys sold one that only ever did local racing for $6M last year, so I put my estimate in the middle.

330 P4 is also hard to price, none that sold were ever disclosed that I found so it's all estimates.
