But at $40/month for insurance, you likely have liability insurance only and a gap in coverage if you hit a car > $50k or significant medical costs. Most states have tax depreciation/deductions per mile that are considered by most to be much lower than accurate. In GA, it's $0.55/mile (real costs were estimated $1/mile at $4 gas); so, at $30/gas, you're being very "efficient" because it should be costing you at least $150/mo for that kind of mileage.
