Plan on looking into getting a rx at the end of the year. Really wanted to buy used but if the price vs. Price isn't right I'll see what new has to offer. Is there a big difference between the 16 and the 18s? I just started looking on here and figured maybe some people that owned both could give some insight. Thank you

 

There's standard LEXUS Safety System+ and 10 years complimentary Enform.

I noticed they deleted the A/C button that directed the A/C to the driver only when selected. the 2018 pushes A/C air to the back seat (NON "L") only when someone is in the back seat or you have a suitcase or box on the seat, i.e. a load on the seat. Otherwise the RX350 is about the same,. The automatic back hatch opening device is better (more sensitive). Appears to me that the Auto Brake Hold is more sensitive to the gas pedal, more refined. Pretty much the same.

 

I say always try to buy new, maybe wait for 2019. Each year, they fix something.
Remember, you can negotiate about 15% off the MSRP on a new RX 350.
