Semi truck prices can vary greatly depending a wide variety of factors, including vehicle age, condition, and the current market situation.
You can compare prices on the following sites:
The average price for the cab alone (where the engine is, and from which the driver controls the truck) is in the area of $130,000 to $180,000. The cost of the trailer is another $30,000 to $80,000.
Some of the reasons a truck is so much more expensive than a passenger vehicle is the ruggedness it requires. While a car engine may be designed to last for up to 200,000 miles of driving, a semi engine is designed to run non-stop, and drive at least 1,000,000 miles before needing to be rebuilt.
