The company cant be expected to cover your wife's desire to have an expensive car. I am willing to bet they pay that amount regardless of the car the employee drives. Get rid of it and get a Ford Fiesta or Focus.
Exactly, she is lucky with the rate she gets. Especially considering that she's writing it off @ end-of-year anyway. Car reimbursement depends on the size of the company & the work involved. I've worked for Fortune 100 companies in the past where the actual car & all expenses on it were paid for. Other smaller companies would only reimburse you $0.15 to $0.20/mile for work related driving. Just because govt. employees get paid $0.50+/mile doesnt mean the private sector has to or will duplicate this. People always tend to abuse this perk anyway, so I understand why it varies widely.
