I, like some others, keep an excel file with every penny spent on the car. This includes mods, maintenance, and gas. It also gives me a way to track how much i've driven the car down to the mile. Yeah, i'm one of those people haha. Anyways, I bought the car on 12/5/09, and since then i've driven 17,416 miles, spent $2,857.30 on gas, $1,497.21 on maintenance, and $6,079.25 on mods.
