If u want a sturdy, spacious, powerful, euro 4, fully loaded (with added safety fetures like dual airbags, abs, ebd, built in door crash beams) then go for V2.
No offence to anyone but in wagon R u would always be afraid of cutting sharp turns.
If u r talking about resale.....i personally think that next year when Pak Suzuki and Toyota launch their new hatchbacks, the reale of wagon will be adversely affected. This is only bcoz wagon r, quite frankly, is not a very attractive looking car.
