l am thinking of buying a used one with low mileage, are they good cars, and how is the longevity, gas mileage, factory stereo system, etc.?

the junkyard has them

Junkyards have them, as well as most other cars ever made.

l never heard of any major problems with used SF's. Plus, l believe you will get the remainder of the bumper to bumper warranty (5yrs 60,000miles) so l think their worth a look.

It gets decent mpg but not the best in class.

The ''SE'' and ''Limited'' models will have the better stereo systems as options which the top of the line is a 10 speaker 605 watt Infinity system.

l think you should consider it, l would.Hyuandai are good cars!

Yah My uncle does.Its a 2006 model.It is a great car.Very comfortable to be in and good quality for a korean car.GOod engine,smooth and efficient.Factory stereo is OK.Its all great.

Good Luck!

l have one which is now 5 years old, a 2 liter diesel. It returns 38mpg and is a pleasure to drive especially in wet and icy conditions. Mine came with a highish end sony head unit and 10 disc shuttle as standard. It is a pretty reliable vehicle.
