I poked around and didn't see a thread like this. So I'm sorry if it's a repost.
But like the title says, what is/are the name(s) of your car(s)? I'll start out.
ALICE is the name of my 2005 Forester XT. From the game American McGee's Alice. Also it's a nickname for the carputer that's installed (A.L.I.C.E.-Automotive Language Interpretation and Computing Engine)
The newest addition, the 1992 SVX LSL project car just got named last night. "River" is the chosen name from joss whedon's FireFly/Serenity.
