This is already pretty common in other markets. In Italy for example the percentage of people or companies that rent their car for 24, 36 or 48 months is increasing faster than normal sales. Basically all companies offer this service, either directly or through long term rental companies.
I'm renting mine. Instead of buying my over $90.000 car, it's costing me around $700 a month (after tax returns) including road tax, full insurance, maintenance, tyres and a premium service. If I'm keeping the car for 3 years (which is the scheme I preferred, but I can change this along the way if I want to upgrade to a bigger or newer one, of course this costs extra), so in the end it has cost me $25.200 for those 3 years, while the depreciation of the car alone would be more than that. It's a win win for both the consumer and the seller not only because you'll change cars more often, this scheme invites people to rent more expensive cars than they would have bought, so the seller gets a higher pay out than he would have had selling a smaller car and he can earn money on the same car again when selling it after only 2, 3, or 4 years.
