I need your advice

For many years, my father has always had a 350 SLC in the open (covered under Carport) The condition is as follows: Thresholds have to be re-inserted, since the previous owner removed the jacks. The paint dress is in spray can quality. the lower area of the body (the wavy area under the trims) is spattered and looks dirty! So this area also has to be re-inserted. The brakes are over, chassis rubbers porous , the Brem power amplifier leaks, engine is oiled and valve shaft seals are no longer in order… (stands 10 years ago) The car had to venture away from its place as a storm destroyed the carport roof. Since it did not slip, I went to work to breathe the engine back into life after 10 years of service! after three trying the engine ran with a pleasant and clean v8 sound. I then drove the car to its new parking space and fell in love with the car. W If you read the condition of the car like this, would you like to repair it again or rather slaughter it? PS: Amazingly, I didn’t find a new rust in the bike runs… It also looks rust-free in the trunk. Thanks for your help
