I currently own a 2014 Es350. I've been extremely happy with it so far. It's probably one of the most comfortable and smooth riding vehicles on the road. New circumstances require me to drive an awd with bigger trunk/cargo space. The new RX350 seemed like a no brainer especially with the updated look(which i love). However, the droning and vibration issue scares me. I'm also thinking about a 2015 cpo and was wondering how the ride is compared to 2016+ models. Any input would be appreciated, thanks.
