My '90 350 SDL caught on fire in the fuse box this a.m. Now what do I do? This car has 320k miles and was running fine. I didn't notice a bad fuse before the fire, which was small and mostly smoke.

Do I try to have it fixed and will it be expensive? Small things are starting to go wrong on this car - mostly electrical stuff, but I'm worried about pouring money into it. If I should get rid of it, where/how would you market this car? Help! I'm poor and need a working vehicle!
