The SRX handles well, especially on highways; but visibility is an issue. The rear view mirror is too small so you really need those side mirrors. Having the defensive driving add in helps. On the highway I have managed to get 24 mpg. The CUE system needs some major improvements as it is totally non-intuitive. And the HD radio can go as it just makes it difficult to hold on to a station.
speed handling is good.
Dump the CUE and find something better. At least make it so the dealer can do add on applications.
