$34k won't get you much in terms of luxury. Lexus and Buick (somewhat) are the only reliable premium brands right now. If you need a European brand, Audi is the most reliable.
Take a look at a new 2017 Honda Accord. The main reason is because you will get massive incentives as they are trying to get them off the dealer lots. Second, they are very nice cars. I had a fully loaded Accord Coupe a long time ago and it was a very nice car for the time. Not luxury or prestige, but comfortable, stylish, and reliable. The new one is very stylish still. Honda stopped making the Coupe for 2018, so find a fully loaded 2017. For a more modern design, the Honda Civic Coupe is a newer model that should be pretty reliable. It is smaller than the Accord, but its a coupe so its not a high priority. You won't get those incentives on this one.
The Buick Regal Sportback may not be a bad choice. It is new for 2018. It has the styling of a coupe, but has 4 doors. I know NormT will promote it. It probably won't be reliable in its first year like most cars. If you want a quieter cabin than the Hondas, chech this out.
Test drive the Audi A5 because it is a good mix of luxury and fun. I think it would be over your budget so look for a used 2018 A5. I've never liked the Lexus RC much.
