I liked the original car maintenance schedule idea, and this is not to be considered to be raining on your idea (it is smart and good sense), but do you already have a pc with a simple database to document these types of things?
I would guess you do have a pc with notepad at 1 end of the spectrum to a spreadsheet, to some kind of database perhaps at the other end of the spectrum.
We all do. (If not Google provides great free items like spreadsheets and documents.)
Yet I don't know anyone who actually copies invoices and receipts to these or even scans them in, which would be even easier.
My guess is we don't need eHome to do this as much as discipline to do it at all. The real question is does anyone really itemize past mechanical expenses.
As I write this I found out that my wife actually does document all her car maintenance expenses via her "My Ford" page , so what do I know?
Hey Steve, erase my post.
Anyway as long as your wife is good about entering the stuff in eHome, then everyone win/win...
