Can I deduct new car purchase: I use my personal car for work. Company uses MOTUS a FAVR plan to reimburse. Can I deduct purchase of a new car?

I bought a new car (paid cash) and kept the old car to give to my wife.  I use my personal vehicle in a sales role at work. Company uses a FAVR plan called Motus to reimburse some expenses and some mileage.  Can I write off business use portion the purchase a new car under this arrangement?
