Actually Bart, you're not alone on this. It's hard to blame deer, foxes, moose or any other wild anmial for these kind of accidents when there really is less and less space for them to live, and while some of you may not care, I personally don't wish to see any more animals go extinct thanks to us
Now, back to the original thread, if any of your damaged parts are not VX specific, then yes, there may be some aftermarket parts out there, but shoot, half of these forums talk about aftermarket shocks, exhaust systems, lift kits, etc
so if the warranty is the same as OEM and the shop doesn't see an issue, you should be ok, there are also some states that mandate the use of AM parts when available,
remember, the shop won't put anything on your car that makes it look like crap as their name and rep is riding on you being happy with the repair too
hope this helps!
