Which car Should I buy? BMW? HONDA? PORSCHE?

BMW has the worst reliability as they are always breaking. I've seen so many issues with window regulators as well. My Aunt had a BMW convertible and we had to get out of the car and help the motor by pushing the top down. No matter how many times they serviced the car for the convertible top it would just do break again. Honda's are nothing special. Everyone drives them, Its SICK. Just like Toyota's. Porsche Boxters are very nice. If you have the money then go for the Porsche. A used one in the model year is only like 12-15 thousand.
