I drive the exact same number of miles every day and with about 2 1/2 hours a day in the car who the F*** cares about depreciation. I replace my cars every 4 years and I drive what I want.
For you guys that don't see it that's a 1 years worth of a 40hr week for every 4 years on the job. If I'm going to in the car that much I want something nice and fun.
