the vti has a steptronic transmission with sport mode and steering paddle shifters
as for the disadvantages I think its a little bit pricey even its well equipped with original honda supplies, I don't know but I can tell you about the features it adds to the basic lxi like:
alloy wheels, side curtain airbags, turning signals embedded within the side mirror, chrome exhaust finish, roof opening, xenon head lights, USB, Aux in, Automatic sound level adjustment , leather seats, vehicle stability assist system, mmmm...
thats what I remember ,I think its a very good deal and am gonna buy it ISA
