Rao,
Check with Carclub (i think thats the right name) on defence boulevard. They had couple of 2003 onwards shaped surf for aroun 2Million or so but this was when i checked 3-4 months ago. Try the showrooms on defence boulevard.
My suggestion would be to go for surf may it be new shape or old shape. Prado is kinda stigmatized in our soceity atleast IMO. Normally associated with SHEEDAY MEEDAY and GHUNDAY BUDMASH.
In my opinion, when you are in ur early 30s - Go for surf
In early 40s - Go for Prado
In early 50s - Go for land cruiser. (i.e if u really want to stick with toyota brand)
