OUCH!!!!
That's not good...not good at all. You can transfer the N1 Dual exhaust..but I have second thoughts on the intake since there is a different one for the 95/96 and 97/98. You can use the headlights...but you have to change the WHOLE front end. I know this since I 've done this to my car.
You can total your car, buy it back and find a 95/96 while parting out the current car.
OR
You can have that girl's insurance pay for the damage....since its obviously her fault. If that's the case I have to mention that parts for the 240SX are not cheap. It will cost you around $500+ just to replace the bumper and taillights......but hey...YOUR NOT PAYING FOR IT.
