This is just my opinion; take it with a very conservative grain of salt, because I'm often wrong.
Despite the fact that this is likely a very high-quality project, I get the definite sense that people jumping in on this one are just doing so because they're happy to see a legit ICO with some legit partnerships, good roadmap, good whitepaper, et cetera and they're wanting a piece of the "ICO pie." Where it fails is that being a "slow burn" or longer-term investment, the plethora of money-hungry investors looking to get in on an opportunity to "get rich quick" are going to be disappointed in the growth of this token's value against Bitcoin and dump it when it doesn't make them millionaires overnight.
Furthermore, we're going to start seeing a shift away from car ownership as self-driving technology becomes the norm; more people are going to care less about owning cars, and they'll more likely choose to pay for a subscription to a network of self-driving cars for on-demand transportation, so the used car market is going to become less and less relevant.
Side note, what about DIY mechanics? I trust my own work over that of a dealership's mechanics; I realize that isn't the norm, but how would I enter my own maintenance activities to a blockchain-based log, and who's going to trust these entries?
