The F1 car doesn't cost 60 pounds unless the person buying it is intentionally buying the smallest token pack repeatedly to... waste money and prove a point, I guess. It should not come as a surprise that the bigger packs are cheaper on a per-token basis. Not saying it's worth buying the F1 car with real money at any rate, though... at least for me.
I assume the 100k/hour comment doesn't take into account how much money a player can rake in rigging Rivals. I haven't played, but I assume the method I used in FM4 works fine; just target the person directly above you, even if it's 0.001 of a time difference, and sandbag to finish as closely to their ghost as possible while remaining ahead. Rinse and repeat; I earned literally millions from each Top Gear Rivals event by doing just that.
It's interesting that people are bothered that one of the cars will be locked up from accessing until a month or so in, though. I admit, not having the whole lineup in Free Run is disappointing, but considering GT5 locked the vast majority of its car lineup behind not just high prices, but a completely random and too tiny used car dealer, I don't see it as too criminal that two cars are worth 6 million in FM5.
What's more shocking to me is the apparent lack of free upgrades with Affinity. Now that's where I saved a ton of money...
