@ wittycranium,
Sorry for the late response since I saw your reply just today.
1) I suppose it would shed around 2 to 2.5 lacs in a years time since there are so many on the roads these days.
2) A TZ version would have dual A/C and is a 7 seater.
3) As for the wooden panelling, I'm not sure if there is any place where you can get a decent one for a Prado. However if you are really interested to purchase through me, I can give a few people a buzz and find it out for you.
Regards
