Both my vehicles have a logbook (actually a cash book) which we write down gas purchases and then any work done. [I sometimes will note tire psi, tire depth, random stuff like that.] It slowly migrates into Excel mostly for mpg and cost tracking. When the vehicle is sold the book might go with it (my last car) or kept (wife kept her Civic book and simply started a new page for her Camry).
We tend to buy boring vehicles, run to highish miles, and usually no one cares about this sort of thing, so I'm not putting any real effort into it.
Receipts get stored with all other receipts in the basement, in case of audit.
