Its a company car not your weekend toy. Buy something newer that will allow you to take 3 people if need be will not be a nightmare to drive in the winter. As for power who gives a fuck its not your car. As for comfort since you are transporting clients think of then not yourself. Why you ask Its not your car.
the cars you should be considering are Camry, Accord, legacy, Malibu or any other car in this segment. and get a car with a 3 year lease its your work car its not your toy to play with on the weekends.
