Cutting a long story short my 95WRX met a telegraph pole last night. (Lent to a friend, onlt covered 3rd party and no other car involved) It hit the join between the passenger door and the front wing, the A-pillar dented and the floor's buckled. Whould anyone know where I could get a new shell from, or have any other advice?

 

Sounds like the chassis has been bent, if so then you will need a very good garage or like you say a new shell.

Being an older car you may beable to get a shell from a breakers or from someone who has been rallying & wants an upgrade.

Otherwise I would give the car to your friend & take a lot of his money & buy another car.

Remember reshelling the car will affect its value when reselling.
