Very nice and organized sheet. Looks quite professional. I went the simple route and use my google drive and downloaded "Google sheets" on my iPhone to keep track of costs. Mine is much more simple with everything just added in the next line down with a section for "notes" such gas, parts, registration etc.. I wasn't really looking for a cost breakdown, though, just tracking costs. So far I'm at $0.59/mile.
I love data!!!
