Need some advice.

You don't have many options here.

You clearly stated that you do not want to sell the pickup and your parents won't let you keep two vehicles so that pretty much ends it right there.

It's a fact of life that we can't always have everything we want, when and how we want it.

In your case, the Mustang will have to wait as you've already chosen the Toyota pickup as your main vehicle and are attached to it. You want a Mustang but you don't have a Mustang so you haven't lost anything here.

In a few years you'll be old enough to own as many vehicles as you want and can afford. Until then, enjoy your pickup.
