I'm looking to buy another lexus. Any recommendations? Years? Trim? Things to look out for?
Any input is muchly appreciated. Even a current pic of your ride

I used to own a 2nd GS. Great Car.

 

Get a low mileage 2013 - 2015 with Nav at least since then you will get most of the other popular options. All the prior model years problems had been corrected by then.
If you just get a certified Lexus it is hard to go wrong.

 

I was in your shoes not long ago......I was driving a 2007 model, never let me down, I DROVE that car, I plowed through snow, I took in on gravel roads, it served me well. I wanted a change, and was eying a newer model. Here is a link of 2014 giving a few specifications:

I really like the more modern looking headlights that started in 2013, but I think I won't be "plowing" through snow drifts as I use too, the front has too much to damage. I settled on a 2014 Fsport after looking at several cars. Condition and lower kms was high priority for me. I suggest you test drive a few. One feature that I have that surprised me is the heads up display, I like it a lot more than I expected.
Make a list of your "must have" options and start looking. It's hard to get everything, I ended up not having the optional heated steering wheel that I wanted, but found a car with every other feature, in the colour I wanted, and fabulous condition. The one disappointing observation I had from several cars is the poor shape of the leather seats. I find the ride firmer than the 2007, but very acceptable.
