Is it possible to add miles on the odometer?

I have seen people drive 50K in a year. I have had many customers that drove over 3K per month. You bought a salesmans car. Don't be afraid of the high mileage. They know they depend on their car and keep up on maintence. Highway driving is when the engine runs the best. A car driven daily on short trips without the engine warming up would have valves packed with carbon build up.
