What is the best vehicle to own?

i already got the mercedes benz S 550 just recently but i want to get something that i can use for a nice warm day so im thinking of getting the SL 550 roadster because i took it for a test drive in the dealership and i loved it. i definately signing papers for that car in about 2 weeks. i always lease though. i don't like BMW because they are ugly and not luxurious enough for me. i don't know should i get the SL roadster or the porsche cayenne turbo or what should i get? i really don't know what is hot because im soo busy running by businesses i don't have much time for myself i don't know what is new. help me, what car should i get? don't say ferrari or lamborghini because im not paying too much over $100,000 for a car, that is ridiculous.
