Some of these opinions are all over the place and dont compute. Take the company vehicle, they pay for the fuel, the maintenace, the insurance. Your car is way too old to pile on 25,000 miles per year. There has to be a reason they are giving you a van, are you hauling things, if you are broken into on your personal car is it covered? If you tell them it is for business your policy will jump. There are questions, how will they treat personal mileage (an easy fudge) I had a 25car fleet they were replaced every 4 years and or 65,0000. Our people were not re-embursed from the mileage to the first sales call (IRS) issue, but they figured out if they went to their post office box for company "mail" all mileage is buisinees and they padded the logs. We finally gave up let them drive the cars, reasonably, and re-emburse us for their personal mileage. (IRS)
You will find keeping records, and using your car as a buisiness tool is envolved, your customers will not be impressed by the MB vehicle, but rather by your skills and common sense. Your .60 cents a mile is reoprted to the (IRS) If you are really serious, lease a vehicle, and write off the lease payments agaist you car allowance, otherwise you could be taxed if the company paid you more than you can justify items as operating expense. If you had it washed, company pays, if you do it does not apply.
I had a $100 million, operation we offered a 4 year opt out, (for ego people who wanted Cadillacs rather than Taurus)) and they all came back as their leases came up...whining!
