For me it works like with scents. Many people choose a new perfume specifically for vacation so that later, when they smell it, they instantly go back to those memories. With cars it works the same way for me. I agree that if you’re renting a car, then it should be something unusual. For me those are cars like Ferrari https://scuderiafans.com/enjoy-ferrari-drive-yourself/ . Modern rental services can offer options like this, especially in big and modern cities like Dubai.
