When it comes to car service records, unless you have the VIN numbers and information to connect the service provider to the car manufacturer, I don't see that being done. It is possible to manage it from a database, but the downside is that there's no single point of view to get the data out, and you're relying on people to enter the data accurately. That’s where blockchain has an advantage over a regular database.

You could draw a parallel with the healthcare options in the US right now. There's telemedicine, urgent care, hospitals, and then your physician. Now, in all of the doctor's offices, there are signs that say, "Use your primary care physician because they have your history, and they can better manage your care." And this would be the same token in that the individual is the one who’s responsible for that information. So, you can manage it through a database, but somebody has to put the data in there and connect it all.

Blockchain technology should never be a database replacement, but rather a component of an overall architectural solution. Storing large amounts of data, such as service records, would be very inefficient and not performant to actually query, create reports, etc...

One option is to store the hash reference on-chain that points to another secure datastore. I've used a combination of a private, Proof of Authority Ethereum blockchain + IPFS to do this.

One word is Trust. As a third party, people are more comfortable in a non-editable central placed than one's own Database
