OT: What would you do?, Sell or store the DD? Options

[type11969]

Starting next fall I'll be going to grad school full time in Philly (Drexel Univ) for at least 2 years. Since I live in Philly, I basically won't need a DD anymore. I'll be biking or taking mass transit. Actually, I won't need any cars but hey, the aircooleds aren't going anywhere. So the question is, do I sell my DD Miata? Well, for those of you that loathe Miatas, pretend it is something else. Its kinda beat up from being in Philly so in a market of low mileage always garaged weekend warriors it isn't worth too much, maybe about 5k (vs 7k+ for a primo example). The thing is, in 2 years when I start working again, it will probably be nice to have a DD again with AC, etc. I probably wouldn't get another Miata if I did sell this one, but I certainly wouldn't mind having it because its reliable, I know its history, and I generally don't give a shit about it. I also have the option of storing it for free in my parents garage up in NY State. So this is the way I see it

1) Keep the Miata, store it in my parents garage, pay minimal insurance if any (no-op), potentially deal with mice, and then in 2 years (maybe 5 if I stick it out for a PhD) I'll start using it again.

2) Sell the Miata, get about 5k, then in 2+ years buy another DD spending at least 5k to get it (taking a gamble that the "new" DD is as reliable).

I see pluses and minuses to both. I'm not hurting for cash so thats not an issue but I also obviously don't want to throw money away. So what would you do?
