I had no issues getting rid of mine, but only because I'd stripped it back to standard so it didn't even feel like my car any more, and also because I was fulfilling a dream by getting the 911. I miss it, and I'm sad because I didn't get time to do all the mods to it that I wanted, but because it was the most manly car I've ever owned I didn't feel a great attachment to it the way I did the VXR or the MR2.
That's not to slight the car as it was an absolute hoot for the 3 years I owned it, which is the longest I've ever kept a car, it was just a case of moving on.
