Thanks for the help.
There's a catch. Life token has been paid against previous 1000CC engine. Now what will be token tax situation, considering new engine is 1500cc???
Plus, my father contacted the 15 office and they said the new engine must be updated on book before bringing to 15. Strange...
Do they physically check the engine and chassis or just the vehicle book is enough???
And can I get the clearance against the old engine???
