Sucks to hear. Hopefully your sister was unhurt.
Radiator, AC Condensor, plus all the straightening that is needed - likely by themselves will total out the car. Never know though - depends on the how badly they got hit. Parts are pretty plentiful, and as long as the engine and powertrain are in good shape - the car can be rebuilt. The real issue will it be worth it. Depends on what you need the car to do, the shape of the rest of the car.
At this point, without looking at pics or details on the rest of the car - I'd personally consider it only as a fixable commuter car or potential project car for fun. Even at relatively low speed impacts, any sub-frame tweaking needed to pull the car back into shape generally results in the car never driving it is did pre-accident.
Yeah, thank God she's fine! So I decided to take your suggestion and use it as a commuter vehicle. Sounds like a good idea, especially since it has 69K miles and thus a few good years left. SO, I called up a local repair shop, and I was quoted around $550 to repair the vehicle. Figured it was worth the money. Basically, it needed a headlamp, parking light, radiator, grill, and the hood needed resurfaced/straightened out along with the crimson bar. I go to pick the vehicle up today, and it was dead. Stone cold dead- like it was after sitting for a week after the accident. Tried to turn the vehicle on, and no dash lights came on- the door open light wouldn't even illuminate. I wonder exactly what could be wrong with the car--- she hit a truck with the right front of the Corolla, but I didn't think she messed with the electrical system at all. A friend and I managed to jump the vehicle using his Mini and a few minutes of waiting for the battery to charge. However, I'm quite worried about how the car dies that quickly, especially since I was there Friday and the car started.
I'm starting to think that the repair shop is messing with me, especially since the car was cold dead after sitting for three days. They must've jumped it right before I got there on Friday.
And I forgot to mention how the shop forgot to change the grille, so one side is broken and almost hanging from the front. They also left three big dents on the hood after "resurfacing" it. Adds to the car's aesthetics!
Any suggestions regarding the electrical system? It's pretty important!
