re: How much should a company truck affect your salary?

Is the truck necessary to do the job, such as delivery or plumbing where tools and cargo are part of most days? If so, then the truck is worth nothing t you, the employee. They have to provide it or you can't make them any money.

Is the truck very useful and handy because you travel a lot for work within a 2-4 hour area, such as a salesman or project manager? If so, the truck still has minimal value to you as you don't want to be racking up 20-30k miles/year on your personal car and risking it at jobsites, even if you get mileage. Again if they don't provide the truck to a traveling salesman covering lots of miles, you can't provide much sales to them.

The other side of that coin is if you use the truck in-town or for airport runs and it's not really necessary to the core of your job description. Thats worth something to you, as you don't have to buy a car of your own now. Maybe $15-20k/year. Figure a truck is worth $50-60k and you keep it 3-4 years.
