When you work on a construction site, whether you're helping to build multifamily housing or office buildings, or anything else for that matter, you need to have the right car for the job. Hauling around tools, driving around on building sites- these are all things that you want to feel able to do with ease.
Many people opt for the classic pick-up truck, and for good reason. It is generally the perfect car for the job that's being asked of a vehicle on a construction site. How classic is the image of men sitting in the back of a truck, dirty from their day's work, heading from a construction site to the parking area? Obviously, there are other options, but why mess with what is known to work?
