Hmm.. Fishy it is. Are all the tires manufacturer in Jan 15? Did you checked spare wheel's date ?Also are the specifications of the tires matching with the version? I mean are these tires undersized? And, you have not yet clarified on the buttons of tires. If the tires are Jan 15 manufactured, ask them if they have replaced them? If they say Yes, ask them the reason. We will discuss it here. Meanwhile find out manufacturing date of the battery. Also see if the ODO of their present TD car is working? And also let us know date of dispatch of this (oone which is offered to you) car from factory to the dealer.
