Gonna be pretty honest here: I'm not entirely sold on that idea of the roulette being purely based on luck.
I've been playing for nearly 18 months, not a single time I landed a Gr.2, which you'd expect to be somewhere between Gr.1 and Gr.3 in terms of rarity. Of the three LMP cars I've won so far, two have been gifted twice (one on last year's birthday). I've got three Petronas-flavored W08s, while the Color Variation has only popped up once. I'm still missing four Gr.3s, with three of those I own amounting to about 24 copies. I'm missing four Gr.4s as well, with the Mustang being the runaway inconvenience at 8 copies, with a couple others trying to catch up.
My brother just casually plays every now and then, and even then still has had his share of consistent disappointments like the NSX Gr.B and Ford GT LM Test Car, both of which I miss on my own garage.
Then there's the XJ13. It just sounds too fishy for me to land it before attaining, let's say, something as futile as the Red Pig, which is 10 times cheaper. I just refuse to believe the Brand Central-acquired copy had zero weight in this dice roll, what even are the chances of getting a 20M unicorn versus that Cayman GT4 that eludes me to this day?
Some gifts just seem too convenient to be fruit of pure unbiased luck.
(PS: am missing a Miata as well, except it's the older model)
