Tips on Buying Cars: Insurance, 2000 cadillac deville dts, hyundai tiburon

Question
I forgot one more thing sorry which is higher in insurance between the two cars the hyundai or cadillac?

I asked this question earlier

I am interested in getting one of the two cars from carmax.  a 2003 Hyundai Tiburon GT V6 2D Coupe and a 2000 Cadillac Deville DTS both have the same amount of miles 80,000 and they are the same price $11, 998  what is a much better car which one breaks down more often the cadillac or hyundai someone told me a cadillac breaks down more often then a hyundai.  Also which is more gas expensive and which is cheaper on gas.

Thank you for your time.

Answer
The Hyundai will be more reliable than the Cadillac and will use less fuel.  
Personally, it's hard to compare the two cars though as the only similarity is that both have wheels, tires and a steering wheel.
If you're really concerned about reliability and gas mileage, both should be avoided.  Check out Consumer Reports magazine.
Good luck!
