brother car engine was good but you said yourself its been parked idle for 2 yaers outside your house....i dont think oil would have been changed what to speak of filters/spark plugs/etc.
standing outside in cold and extreme heat what will be condition of wiring you can better imagine.
with that in mind do you think its a good idea to restore the vehicle.
keep in mind that "hand off" to restore is a bad idea. you have to be there daily to supervise each thing. otherwise your bill will be twice cars value and you will end up with a poor job
also how much rust is there... you do know thin quality of mehran, rust wont be permanently fixed, many mechanics will simply paint over for fresh look..
keep all factors in mind.
if you do decide to go for restore, supervise the job daily otherwise you will be disappointed.
