You are not mature enough for any project car, if you are willingly diving into “project car scene for daily and drifting” and have exactly no experience in whats what then you will have a rusted out scrap pile and would have lost all of that 2 million rupees too.
Therr are way too many cons out there and when you find one good one, you will have to understand that project cars are in constant repair because they dont follow any manufacturer spec.
The balance is how much time it spends in shop vs how much time it spends on road, and this is why you need to understand how exactly a car is put together, down to little nuts n bolts, so you can actually measure what you are recieving as work.
E.g. older cars like e70 corolla have greasable suspension, wheel bearings and other parts like hinges etc, but no corolla after that, so it has more maintenance just with that. (Most new mechanics dont even know how to set the preload on wheel bearings anymore - so its best left for diy)
Then comes the part that you have a 40 year old car, stuff will fail for sure, and at odd times unless you literally strip the car to bits and rebuild it 100% (which again requires 1st hand knowledge)
