Such a load of BS. The only way to obtain them would have been to buy 5 copies of the game at specific retailers. Same crap happened with TDU2 but luckily they became available for download a few months later.
I agree that the separate pre-orders is kinda ? but the pre-order period is fine. Should be a way for everyone who pre-ordered to get a crack at other pre-order cars. No way a game company is looking for a guy to pre-order 5 copies of the game
I could see if maybe they gave away a car for each place that had some sort of special paint job, but it is silly to do it with common popular cars like the 1M or STI.
