I'm in much the same boat on the Plus account, only all 3 of my remaining cars, including the 250 GTO, are of the 20,000,000-Cr. variety and I won't have 30,000,000 Cr. by Thursday. On the GTP account, while I have all the cars, I'm currently under 10,000,000 Cr. a tick over 12,000,000 Cr.
I'm anticipating the GT-One being at least 10,000,000 Cr. based on the fact that the only mid-to-late-1990s Le Mans car (or its road-going variant, just in case we get that version like we did the Porsche 911 GT1 Strassenversion) that isn't 8 figures is the CLK-LM. It is, of course, a small sample size of 3 Le Mans cars and 1 homologation car, but given Hagerty's influence and the fact one of the 1999 GT-Ones won its class and was 2nd overall, it easily could be the 14,000,000 Cr. the F1 longtail is or the 15,000,000 Cr. the F1 shorttail was before the 1.43 price updates.
