Amateurs...
You ain't rich enough to pull it off with a single car. But I'd give you a basic model how the riches do it without being caught.
1) Create a car rental company in AB
2) Finance exotics under that company and register everything in AB
3) Buy "FLEET" insurance, write off all maintenance, parts... etc
4) "Rent" the exotics to another entity... possibly to the company rich dude has.
5) Barely makes a profit hence no tax
6) Dude pays all the exotics with gross income (as in before taxes) and deducts pretty much everything.
