I purchased the I30 off lease in February 2000 with approximately 28000 miles. It now has 134000 and is still, praise the lord, running well. So far only minor problems dealing with general upkeep. The car remains solid and fun to drive with no noticible rattles. We were going to trade it in recently when we purchased a new vehicle, however I couldn't bring myself to part with it! It's a great automobile.
Bose audio system and overall comfort and driveability.
The auto is 11 years old now and a little late for improvements.
