There's been a few threads about this. Maybe it's time to have a sticky showing that the vast majority of users in this forum do DEFINITELY recommend the option.
I myself, doubted a little bit at the begining if it should be part of my future build or not, but reading the other threads had me convinced.
There even a few posts of people who didn't get it, asking around about modifying the car.... It will never be the same and it would be a lot more expensive. With all the functionaities built into the package $900.00 is actually a very reasonable price!
