1- Is restoring a full time job? I mean I work from 9-6, can I still manage?
No, restoration is not a full time job but still it requires some time n good effort which gives lot of mental satisfaction.
2- Is there a phenomenon like I leave the car at denter's place, he does all the denting job, then I take it to the mechanic who fixes the engine and then to the painter who paints it? Or these things aren't that simple?
Yes, these things are simple but when you are doing it practically you gain a lot of experience. And yeah you have to leave car for denting , mechanical work and paint job at workshop. So try to locate good workshop on a first step.
3- How hard would it be to find the spare parts of this car? I mean I know it wasn't sold much in Pakistan, can I still get all the spare parts from Bilal Ganj?
I don’t know much about parts status in Pakistan but I can surly say they must be available abroad somewhere.
4- The cost - a rough idea about how much it may cost me?
That depends on your workshop denter n painter but let me tell you this project will cost you little high as you will gain lot of experience through it. So the be prepared on a higher side.
So best of luck and if you need any type of techinical help do let me know.
