If I see a car that is at a dealership in TX, can it be sent to CO? How Much?

That way auto shipping works, is you would need to purchase the vehicle first, then contract an auto shipper to pick up the car and deliver it. It would be ballpark $1000 to do so. Consider finding an vehicle local to you, that way you can test drive it.

I would avoid buying cars long distance. You will almost certainly regret it if you proceed.

Plus any money you save on the purchase price will be eaten up by the shipping costs or the cost to drive it home. But if you decide to proceed please have the vehicle inspected. I've used lemonsquad.com with excellent results. That way you know what you're buying! Hope that helps! Jim
