Miles and dollars: Boxster ownership vs. first car

[Perfectlap]

I thought this might be interesting, once you account for purchase price, upgrades to have it as you like, as well as all maintenace and unexpected repairs, and then divide by the mileage on the odometer that you've clocked yourself, how much has it cost you to run the Boxster so far?

I purchased my Boxster S with 10% of its current mileage already onboard so I'm guessing I should exclude this mileage.

I get 0.73 cents per mile.

My first car, a Honda, adjusting for inflation, cost me 0.12 cents per mile. Never broke down once. Paint was shiny all the way until the end.
