Hi Napster,
If it's done at Dealer, it will cost arnd 20-25k and I think 10k or lesser if done outside. I had inquired at Fortune Motors, Navi Mumbai. They quoted me 20K for just paint and offered me a package worth Rs45k which includes, Art Leather Seat covers, whole interior with wood finish over steering, area around music system and trims over door panels.
Cheers!
