As far as i know u cannot ship cars older than 3-5 years old... Because of the Anti-dumping laws... Also if u get permssion in vintage categories u will have to pay around 100-150% tax ont the value of the car when in new.

Things can be easier if ur actually quiting residence in qatar.

There is a lot of factor in which u shud'nt take this risk

1. U wont get good maintainance
2. INdia is right Hand side driving. Difficut for u to over take in Highways.
3. there are better cars on indian roads now.. Now that all the cars are being made in india... from nissan to BMW and merc.. toyota...

think bout it and make a wise decision.
