General questions about CT and Lexus at all

Good evening, at the moment I drive a 2008 Honda Civic FK3. A vehicle that hides the one or the other in itself which is annoying, but all in all a round concept with acceptable consumption for its performance. Now I have seen the new CT 200h and fell in love. Brochure (the thick) I already got worried. However, I have one or the other question, apart from the fact that I want to drive the Civic at least 2 – 3 years. (…) Lexus is no premium brand. Is that the cost of maintenance? So insurance and tax? What would the CT200h actually have to be tax-free? Besides, I ask myself what it looks like with the normal workshop prices? So for oil changes and inspections. Since I drive at least 30,000 km a year, the cost-effectiveness question also arises. From the stated consumption the Lexus would be far superior to my Honda, which I do not get under 5.7 liters of diesel. Has anyone bought the CT? How is d he satisfaction? What about the Lexus dealers (Toyota), is the premium claim also synonymous with the discount, house price, etc. Foreign words? I ask for numerous, if possible objectively usable information. Thank you.
