Make sure everything works perfectly after it is repaired. It'd be easy for a repair shop to forget a wire that might have been completely obliterated in the fire.
Check all components run by the hydraulic system. Make sure dealership repairs aren't done half-arse, e.g. spicing wires together with nothing but electrical tape (I've seen this before)
I personally wouldn't trust a dealership to do the repair and if you have the ability, please consider a repair yourself. At least you'll know it was done correctly and not rushed.
