It's personal preference as to what you like, some people get 4x4 then want big power and as said then convert 2WD as the running gear is stronger, or some want a 2WD so instead of selling simply convert it, or see a 4x4 they like.

The same thing can be seen on the TV show "Wheeler Dealers" that was a 4x4 converted to 2WD.

Mine is original 2WD and have never had any problems with it what so ever, so that means no broken diffs, going sideways into things etc, if you respect the cars for what they are then there will be no problems.

Launch control is a predetermined rev limit set that allows you to run full boost from the start line, you can simply plant the throttle until the aforementioned rev limit is reached.

Both this and anti lag create loud pops and bangs and is illegal for street use hence it is switchable.
