Currently looking into buying a used

2011 haundayi Tucson that has less then 94,000 miles, but I'm not sure if they are really that good of cars.

- Do they cost a lot to repair?

- Are they pretty gas effcent(not looking for a prius)?

- Do they hold up after time pretty well?

I'm just trying too fit my son that's rear facing in a chicco nextfit carseat and his chicco bravo stroller plus some groceries.

Please give me some advice or recommendations.

Thanks
