Hi, i got a tigra, today! it drove fine for about half an hour to get me home, then when i went to drive it tonight, after about 5 mins it started making a knocking noise from rear end of car, then slowly it got louder and louder... i have NO clue what this may be, but i'm certain it's coming from around the rear passenger wheel....

First, check that the wheel nuts aren't loose. Then, jack the car up on that corner, handbrake off, and see if the wheel will rock from side to side or up and down. This will determine if the wheel bearings are ok. When you are down there, grasp the exhaust pipe and waggle it to and fro. There is just a chance that the exhaust pipe may be banging off the bodywork.
