A project like this already exist, but I don't know if they already started to make something concrete. Worldline created a blockchain for the car market... The cars are included in this open book. Then, each check or repair carried out on the vehicle will be entered in the blockchain.

So no matter from where you buy the car you are still able to know exactly what the car got since its birth

Thank you for your feedback. If i correct understand you, do you mean something simple existing, but with 1 centralized owner?
What do you think, will you trust such system, based on blockchain in case of big data amount inside? And if this data store for a couple of years for different countries?

I don't remember exactly if it was a project finished and sold but for sure it exists. Toyota as well started to develop something like this with M.I.T. since some months

Yes, I will trust such system with no problem but only IF it is added before the car is sold for the first time. I mean it should be implemented at the manufactories level. And if the owners can't add any data themselves. It's easy to fake some things on a car to make it look like the car is new or not so old.

So if someone buys a car then do some things to make the car less old (for example changing the km/miles which can be done within 10 minutes for some money) and then he is able to add the car on the blockchain, it doesn't make the system so powerful.
And while thinking about this, a mechanic guy can easily be corrupted with some money (it is something not hard to find). So if he is able to add data how the system can be trusted.

How to check?
Main idea is to add only data, that can be verified on the previous step. For example distance. Value cannot go to minus, and if owner will make a service, and he want to reduce total distance on the car, system can check with previous value and don't pass new block.

I searched on the web and found this http://worldline.com/en-us/home/inside-worldline/2016/september/when-blockchain-technology-frees-up-car-sharing.html
It was introduced during the "Mobile World Congress" this year around March. Worldline is specialized in electronic payment so not sure why they chose the automotive industry. And the Mobile World Congress is about the mobile industry
