i must say man.......... your grandfather has passed you a car which had his taste in it....... after alot many years im watching an INLINE body 115 being restored......
Wonderful, maashAllah
I can bet that this going to be the best restored beauty in our country, the originals would be perhaps much better.
Mechanical works wont be an issue at all because there are still abundant suspension/brake/steering/engine parts available for these in rwp area
there might be problems with interior things and rubbers etc but i see that are fine in your car
you may top up ur restoration by importing such kits from germany and not use the irani parts
