4 new decent tires for 16's: 70x4= 280
Dent in door: Talk to insurance about your rate or find a place that will do it for a good price; maybe 400 at most?
Drain plug: cheap; if need replace oil pain and stuff, then around 200 maybe
So at max, maybe 800-900 to get the car back to new?
**Also, if you want cheap tires just to put on it that are used or w/e you can find them for like 40 a tire.
Im not claiming the prices, these are only guesses. So, please, dont quote me on prices haha
