I am in feasibility stage for starting a detailing setup + small facility (accommodating 1 or 2 cars ata time) for working on Japanese retro cars like the 1974 - 1982 corolla, Datsuns and other vehicles of the same age. But the challenge is to find some good location in economical rent, I did a small survey in Gulistan e Jauhar and nearby Gulshan e Maymar but a day into the surveys, lock down started.
I was thinking if somehow we can have a car shed with required tools, the car enthusiasts can bring their cars for DIYs or hire the denters and mechanics to do the job for them. Also while designing our house, I tried to keep a separate space for one car (of any size) which could also be turned into a makeshift closed painting facility but plan was rejected by my mother and wife
