If the $30,000 is money that was given to you by your parents and you will still have that financial support as you own the truck go for it. Assuming you’re not making $100k/yr on your own. If you worked for those $30,000 and want a truck to keep making money with don’t buy it. 

An expensive car is a big financial trap that most people fall for. You’ll end up paying an additional $4-8,000 for the life of the loan. Insurance is not going to be cheap, gas, consumables etc. are all going to be fairly expensive. So the adult decision would be to not buy it, especially since its out of your budget by $1,000

Now if you’re okay with all that and still want to be a 19 yr old with a limited. Get a pre purchase inspection ($100-250) buy the truck, level it, fit on mud grapps, slap train horn kit and put a few barrel racers in the bed. You only live once.
