Or it could be like me. I put up the 5k downpayment, the GF gets the Jeep, and I never drive it. Ok, when she lets me I get to drive it, but after a year of ownership, I've only driven it a handful of times, and only twice when she wasn't in it (corner store and back both times). BTW we've been living together for 4 years now.
I'm doing a camping trip and as expected, I can't take the Liberty. As soon as I told her about the trip, she asked "since you're not taking the Liberty, what vehicle are you taking?". A friend of mine (who was already looking for an SUV) quickly decided on a 96 Blazer 4x4 he had been eyeing. Now at least we have a more suitable vehicle for our backcountry trip.
So having the GF get a Jeep is neat and all, but be careful what you wish for, it could turn out like a lot of women... you can look at their stuff, but never touch it [-X
