Sale of Vehicle within different city

I was based out of Delhi and purchased car(2009) and Aviator(2010). Couple of years back I moved to Pune with both the vehicles. Now, I am planning to sell these off and purchase new ones.

Can you please tell me where I could get the best resale value of these vehicles keeping in mind that both the vehicles still hold Delhi registration.

Once I am able to sell these I would need advice for the new vehicles as well :smile:
