I've had used AND new vehicles (all cars, but still).
They both have their pros & cons. It's really up to what's best for you and your budget.
If you go for used...make sure you are getting the car from a reputable seller. Make sure it doesn't have too many miles, either...also, make sure you do a VIN check for any prior accidents. My first car was used, only needed new tires and later I found out it had been totaled 3x. Then, it got hit and was totaled. I loved that car, but it had issues. You should also not go alone to look at a truck/car, make sure someone comes with you that knows a lot about them (not saying you don't).
If you're going for new...make sure you don't get screwed over with interest rates. The lower the interest rate, the better. Try to get low payments, over a short amount of time. I actually had my father go WITH me to the dealer to get my new car. They even gave me a free oil change club card for life so I get free oil changes. Car payments can be annoying, but I really do love my car. It has no issues, all I do is just the regular maintenance...brakes, oil, tires, etc.
Nothing wrong with used vehicles either. Just make sure you don't get ripped off and they don't try to sell you a junker! :)
Ride more, worry less.
