We have both, She drives a 2011 SV6 Sedan, I'm driving a 2014 VF evoke LPG wagon.
we've had the SV6 since new and it gets an oil change every 10K km, 15K is too long. It's just ticked over 110k and no major issues to date. (Clockspring failed and one HVAC actuator failed), I have fitted the SS front disc and caliper brackets for better brakes though.
It is actually a nicer car IMHO than the VF evoke wagon - nicer seats, feels planted on the road, shifts later in the rev range, just nicer to be behind the wheel of.
The evoke is a good car too, the Mylink is better than the IQ, just. Rear camera is nice? Auto park is a nice gimmick, but i can have the car parked and get out before it's picked a suitable spot.
I could change the seats, fit FE2 suspension, etc etc, to get the Evoke to be as nice as the SV6, but i can't be bothered.
I wanted a VE11 SV6 wagon on LPG, but the VF wagon came at a good price.
Also, the Petrol VF evoke is the 3.0L, vs the 3.6L in the VE SV6.
