i'd have to say that maybe they get bored with the car. it happened to me last year. in april of 09 i bought my dream car, an 03 cobra. i threw outrageous amounts of money into it the year i owned it. hardly ever drove it and get it clean as a whistle and in the garage all the time. when i pcs'd (im in the military) and didnt have a garage to keep it in, i paid monthly for a storage just to keep it out of the elements and out of sight for "haters". by the time i sold it, i had just installed a kenne bell blower and it dynoed 605/572 to the wheels. an ultimate and highly sought after car. sold it cause i was paying insurance, car note and storage fee for a rarely driven car. wanting to put it in the hands of someone that would do with the car whats suppose to be done with a cobra, drive it. just my 02 cents. theres absolutely nothing wrong with these cars but i can see people getting bored with them. and boredom will set in with any nice car. kind of like a hot chick youve always wanted and once you get it you want to move on.
