<prompt> Human: I work an outside B2B sales roll. Every Tuesday-Friday I am in the field driving my vehicle.My company reimburses me 180 gives me a 180 weekly car allowance. I typically avg 500-700 miles a week.Through my job I met the GM of a car rental company he told me if I wanted too, and if I was prepared to sign a 6 month contract he would provide me with a rental for 25 a day 100 a week.This is appealing to me and here are several reasons WHY My current vehicle gets approx 24 MPG, his vehicle would get 35 MPG going from SUV to Sedan I would be putting miles on their car not mine resulting in slower deprecation I would not be responsible for any maintenance cost on the rental tires, rotation, oil changes, filters, etc Costs I can easily calculate we assume 600 miles a week some weeks its more some lessSavings on gas:800 a yearTire Rotation: every 6k miles 29 a rotation 150 per yrNew tires 1 set a yr 500 a yrOil Changes use AMOSIL, do every 20k miles runs me 100 a change, 3 changes a year 300Depreciation? Other Maintenance costs? Hard to figure out but renting a car per year would cost me 5,200 and after savings which I can calculate it looks like it will cost me 3,450 a yr.Now this does not factor in: Repair costs alternators, bearings, timing belts, AC, etc the you use a car the faster stuff breaks Deprecation costs: The more miles I put on the car the quicker it devaluesDoes that equate to 3,450 or more? In addition I expect other costs to go up, such as gas I cant see gas hovering around 2 a gallon for everFor example if gas was at 4 a gallon, which it has been been before my gas savings would be extra 900 a yr.  <response>: If you are putting 30,000 miles on your car annually, you would come out ahead by renting, especially as it is less than your car allowance, even if you add in the price of gas.
