A truck has way more utility value so it's one of the few vehicles where it's actually worth paying more for. Even then though I'd go with used but you will pay more even for used.
There are so many times where I wish I had a truck. Even something as simple as needing a sheet of drywall, if you have a truck, you can just go to Home Depot and pick one up and bring it home. If you only have a car you need to pay $50 for delivery, which is not worth it for a single sheet, so chances are you'll put off the project or just not bother with it, or even hire someone. Dump runs is another nice time where owning a truck is great.
My next vehicle will probably be a truck. For something that will last I'd probably be looking in the 10k range, so I'd have to save up. My goal with vehicles is to never go in debt for one. Debt is for emergencies like if a storm takes out your roof or you need a new furnace, etc... You can have a vehicle to get to work (primary use of a vehicle), and not be in debt, by going with something used that you've saved up for. The only debt that really makes sense is a house, because nobody has 200k lying around to buy one cash, and it would take too long to save up for that, meanwhile you'd be dishing out money on an apartment which would cost more than the interest of a mortgage.
Now if you are a business lot of things change. It actually makes sense to lease vehicles because you can claim it on your taxes. So you are always driving a brand new vehicle, AND it adds to the money you get back at tax time.
