Just two issues from a cursory looksee. One, you still have to enter mileage information on a routine basis since it doesn’t know miles driven. Two, I didn’t see anything about multiple cars with the same program. Three I guess, I never track costs like gas and insurance. I just find it a bother and not useful. I record repairs and maintenance and their cost. My main drawback on paper records is knowing at what mileage certain tasks should be done like tire rotation, but a simple post-it note can take care of that. Plus, in my maintenance book, I have everything in one book including small engines, home repairs, yard maintenance, paint colors, etc. Any truly useful software for a home owner would include all this stuff to help manage and not just cars. For computer geeks though that insist, I suppose $30 is not the end of the world.
