She goes into a luxury car dealership, where she pretends she wishes to buy the luxury car that Törzs has just purchased.

The comedy was popular enough to be remade in English as CAR OF DREAMS, featuring a very young John Mills. It's easy to see why; it's very funny. With the two leads to carry the romance, there are two or three comics, including Gyula Kabos as Miss Perczel's gossiping boss, and Gyula Gózon as her father who wants to play some incomprehensible card game with everyone. There's some romantic scenery that includes a waterfall in Lilafüred in Hungary, All in all, very amusing.
