It’s certainly possible to get a daily driver 2002 at 22 and make it a reliable daily driver and cross-country capable (think I was 23 or 24 and a grad student far from home when I did exactly that). But, it depends on your skill level, available time, money, persistence, and passion for it.
i did have some experience working on cars, a previously fixed up beater to drive until 2002 was battle tested, a willingness to chase parts all over and learn what to do, and willingness to spend hours on the street covered in grease trying to figure out why it won’t run. But mostly, just being batshit crazy.
your experience might be a little better if you spend 20k on one, which I could or would never do (I paid 700). If you can also pay a mechanic to do everything, then hey, awesome. But your going to have to be able to thouroughly trust both your car’s seller and your mechanic for it to all go smoothly.
