I would have to say either an Audi A7 or the new Tesla Model S, oh my gawd. That beast is so advanced. It's one of the best electric cars at the moment, it's fast and it's great with crash tests. It's just too bad it's nearly €100,000, though there's the model 3 hatchback version which is less than 35,000. It's just about as good in my opinion
I am a really real fan of BMW cars cause their design also the internal function which makes me go crazy all the times though and there service manager write my paper for me for the test drive back in day when I was younger so that was my best day though .
If we are talking about Lexus I must say that the most comfortable car I've driven so far is 2008 Lexus IS-F. Later series are also cool, though I feel more comfortable in this particular series. My second favorite would be Jaguar XE. It's both comfortable and economic. I have and if I manage to sell it in this year I'm going to buy the car.
