Was the fire so hot that all your hand tools got ruined? Could you clean them up enough with a wire wheel to make do with them while you buy other stuff? As for what to buy, a floor jack with stands has gotta be high on the list.
Fire was so hot it cracked the concrete foundation, and totally obliterated two riding mowers in a "lean too" into a pool of aluminum. A "T" post just outside the structure got so hot that I can bend it with my foot and hand!
I had vinyl siding and totally burned out in like 6 hours, damaged vinyl/plastic things 40ft away,
The side that had the lean-too had metal siding and totally saved a mobile home about twenty feet away, the side that had vinyl siding severely warped home skirting 40 ft away.
The Garage was loaded, bunch of storage and tons of chemicals. Not sure how the fire started. left 3am for work and jumped in the garage for a portable air tank, didn't smell smoke or anything,....neighbor discovered the building ablaze around 7 a.m. It was not worth saving at that point so they let it burn itself out.
I would not trust a wrench that had been though a fire like that.
What is the goal? To do all your car repairs, or just some random repairs for now?
The goal is I can replace a engine/transimission/wheel bearing/ball joints at my home with enough tools should everything fight against me.
There has been many times in the past we were replacing a water pump or wheel bearing, and come across stubborn fasteners that need drilled/torched/ chiseled/or cut... often driving to town for a new tool.
