There are too many great cars out there to limit yourself to just one. Other cars in the same vein that I would like to experience, BRZ and ND MX5. Lightweight, fun, communicative with far superior build quality so why not. I can only afford one car at a time so at some point the FiST has to go.
A point that I think no one has yet made in this discussion is that for some the FiST was simply the "flavor of the month". The car was (is) just another passing fancy, and once the novelty wears off, it's time to go get another taste. This can be especially true for the heavy modders, who, once they have done all they can to car, need another "fix" since to Hot-Rodders (in general) a car is never done, and once it is "done" its time for something else to tinker with in the garage. They have an investment in tools, lifts, etc in their garage, and if they aren't going to be using them again, there is no point in owning all those tools.

I'm more of the "'til death do we part" type. Divorces are often expensive, sometimes messy. Generally, it is cheaper to keep'er; particularly if you're able to do much of your own maintenance (no marriage counseling) and/or have good help (parents, siblings and inlaws). Wait... am I still talking about cars?
