Why? Does the Reserve or Signature have a louder turn signal? From an earlier exchange I gather not. Is there a heads up display that shows the flashing turn signal? If not I don't know what you're getting at. If so, I wouldn't pay up for that and a whole lot of other stuff I don't want. This Touring has a whole lot of stuff already I don't care about. So far, this is the only problem I have, not "problems", unless you count the user manual in which case no trim line is exempt.You should of bought a Reserve or Signature and you wouldn't have these problems.
Do those models have an inverse tractor beam to keep idiots from tailgating? That I would pay for.
Those upper trims come with 2.5L turbos if I'm not mistaken. I avoid turbos so that's out regardless.
Whatever floats your boat. I have my own sailing vessel, thanks.
