New member Corolla and RAV4

[Crotalus]

Just joined. I drive a '99 Corolla that's about to hit 295K miles. I typically get in the mid 30's or better. My sweetie just picked up a used 2010 RAV4 and that's the vehicle I'm most curious about.

It's a 4 cyl (I'm pretty sure) with less than 40K on the odo. She just calculated the mileage between fill-ups for the first time and only got about 15. Pretty disappointing. She does mostly city (and suburban) driving in the Upper Midwest.

Any comments to kick things off? I'm sure she needs to adjust to the vehicle, but she was pretty discouraged. Anybody got any words of encouragement for her? Words of warning?

Thanks!
