Difficulties in decision making

Hello together =) It’s about the following three cars: – Mercedes a 45 AMG – Porsche Boxster S – Audi TT RS I would like to buy a new car, but I have difficulty making decisions. I would like to have a sporty car, which can only have 2 seats. It doesn’t matter from consumption and from the PS, since all three show the same values. In addition, all are about the same price. The question is, which car does you have more driving fun with? Which car does the car bring? PS more on the ground? I hope you can help me =) GLG
