Not sure if this is the right place for this - I apologise if not.

I rented a car at LAS, we got a Hyundai Sonata, less than 6 months old, with working XM radio. I loved driving it, and it was very spacious (my boyfriend is over 6ft and he had lots of legroom). We pre-paid the gas and only put $30 of gas in ourselves. We did about 850 miles through Arizona (so lots of up and down hills, etc) and the trip computer showed we had 50 miles to empty when we returned it, and that it had averaged 37mpg. It looked good too.
