There are many factors that affect the depreciation and resale value for any type of used truck. While most new trucks will depreciate between 15% and 25% as soon as they are driven off the dealer's lot, there are many variables that determine depreciating rates after that point.
For instance, common factors considered in the depreciation and resale values of used trucks are: overall estimated repair costs over the life of the truck, fuel efficiency and fuel costs over a specified number of years and, even a truck's ability to remain durable and reliable for many years.
Generally speaking, pickup trucks that are considered to be very reliable and provide good fuel economy often depreciate at slower rates and have higher resale values than used trucks that are known to have many repair issues and get poor gas mileage. Also, demand and popularity for a particular pickup truck will also help to slow depreciation and increase the resale value of the truck.
Typically, diesel trucks that are powered by bio-diesel fuel enjoy better fuel economy and efficiency than the gasoline engine trucks. Furthermore, diesel engines used in diesel powered trucks often remain reliable up to three times longer than their gasoline engine counterparts. For instance, most gasoline engines are designed to run for about 125,000 to 150,000 miles before a major engine rebuild or overhaul is needed. However, with proper maintenance, a diesel engine often runs three times as many miles before major engine work is required.
Bio-diesel fueled pickup trucks also produce more torque, which allows for considerably more hauling and towing capacity than gasoline engine pickups. So, consumers that need to tow heavy trailers or large boats often choose diesel engine pickups because of the durability and reliability of the engine when towing heavy loads.
On the other hand, gasoline engine powered pickup trucks usually provide better horsepower and are more suited for stop and go driving in most situations. Also, some smaller gasoline powered pickup trucks offer fuel economy that rivals bio-diesel fueled trucks. For this reason, diesel trucks and popular fuel-efficient gas engine powered trucks, such as vehicles manufactured in Japan, often enjoy resale values that are basically equivalent.
