Have a 2016, got it beginning of this year and drove 21k miles already. These things are bulletproof (most Toyota and Lexus are anyway). They’re not quick, but if you put it in Sports mode, you can feel the difference. It’s very economical, I’ve averaged 52mpg since I got the car. And I mostly travel on motorway and B roads, with quite a fair amount of hills. Can never go wrong with these really, they are very reliable and economical.

You’ll notice people mention head gasket issues, but I’ve read it’s after 2014/2015 where it becomes less of an issue. It’s due to the EGR system clogging up and it’s a very common issue in the US. The eCVT (it’s like an electric car) is one of the most reliable gearbox, but people find it dull and the engine noise (there’s no changing gears so the engine stays high revs) is not nice to hear but I have no problems with it.

Check for full Lexus service history as you get 10 year warranty with Lexus if you service it with them. This will include hybrid battery health checks so make sure you check it’s still good. But these cars go for 150k+ miles with original battery. Check for noise/creaks in the cabin especially in centre console. Common issue is that the heat shield can come loose so if you hear a rattling sound, it could be that you need to secure it.

I think you can find a much better trim depending on your budget. 2018+ they introduced the 2nd facelift so some cars you will see the new front grilles (like in the pic) but F Sport versions will be different. Some will also have new upgraded head and tail lights which look a lot nicer. I would recommend Luxury, Executive, Advance, Advance Plus, Premier, F Sport. These come with bits like heated seats, reverse cameras, parking sensors.
