It's 6 cars that are at 20,000,000 Cr. each now, with 1 each at 18,000,000 Cr., 15,000,000 Cr., 14,000,000 Cr., 13,000,000 Cr., and 12,000,000 Cr., and another 2 at 10,000,000 Cr. (and only one of the 10,000,000-Cr. cars a prize car).
To put it another way, the 23 most-expensive cars (22 in Hagerty's and the Aston Martin Valkyrie, starting at 4,000,000 Cr.), at a cost of 271,600,000 Cr., cost more than the other 469 cars combined...even if the cars available only in the UCD were all priced as "hot"/"special picks" (270,299,455 Cr.).
