tucson: Size, gas mileage etc. Thanks to answers!|||The Santa Fe is bigger and as an optional 3rd row seat. Plus has 2 V6 engines to choose from. For the Tucson you can choose a 4 cyl or V6 engine. Both are good but of course the SF is the more expensive of the 2 because it's more refined. However, the Tucson will save a little more gas. You can find out more by going to Hyundai's web site. http://www.hyundaiusa.com/|||one is in Arizona, the other in New Mexico. they're right next to each other, very similar in size. but i think Arizona would be more interesting.|||I have been to Tucson and they have more up to date style houses.......Santa Fe was on HDtv and there houses look like "Desert" houses
