Buying a new car is the second most expensive purchase in people's life, why would anyone want to have others decide which car will you, or your girlfriend, should drive? Get her to drive all the ones she likes for at least 20 minutes each, not circles around the dealer, try to hit the service road and some hwy.
I drove every single make/model that were on my list, went back to the dealer to drive my current car 3 times before buying it. Never asked a soul what they think about my purchase, the car has to make only one person happy, the driver/owner.
