Purchase advice NX 300h

Hello dear Lexus driver, I have to sell my Mercedes E200 W212 in September, because I am unfortunately not satisfied with the quality at all. My father used to drive only Toyota and had very good experiences with it. Well, I looked at different models at Toyota, I already tested the old Rav4 Hybrid. The combustion engine with hybrid drive liked very well, but the interior was too bad and the trunk is too small for me( 3 members family and at Nachwuc The salesman told me that I should try to get the Lexus NX 300 h, which he unfortunately did not have there (only Toyota operation). I have already seen various videos and am enthusiastic about the interior. A test drive then follows in September, when the old one is rejected. My question to the expert Forumristi is, is there problems with the NX years of construction? So no idea should one avoid the first 1, 2 model years or there are no problems? Which Aussta My driver profile is 80% city(Vienna) but also about 5 times a year highway approx. 5000km. I come to a mileage in the year of 13-15000 km. Since I am relatively new in the Lexus world, can someone from the Greater Vienna recommend me a good dealer?
