Sure, it's buggy and you have to do a lot of gathering but eventually you will get a car running. I've built many vehicles in the game without any issues other than some lag and lack of response. It's much easier if you play smarter, not harder... Get some friends to help you gather the needed items to get the car running. Trust me, this game will be great. Rome wasn't built in a day, sir.

Remove structures_houses.pbo from C:\Program Files (x86)\Steam\SteamApps\common\DayZ\Addons and enter the server you played on. Whether it is public or private matters, so know which one you're stuck on.
