Hyundai. 20 year 200000 mile warranty. But the question do you want a coupe or a sedan?

Here's the thing for me:
Picking out an IS 350 is pretty simple, as there's only one trim level. It's very well equipped and includes 17-inch wheels, leather seats, power front seats, automatic dual-zone climate control, a moonroof and an impressive audio system with a six-CD changer. There's an auxiliary jack for MP3 players, and a Mark Levinson 14-speaker, 300-watt 7.1 surround-sound audio system is available individually or as part of an option package that also includes a voice-activated navigation system.

Available are the Luxury package (heated seats and HID headlights) and the Sport package (18-inch wheels, sport-tuned suspension and unique interior details such as aluminum pedals.)

The Genesis comes with sport suspension, Brembo brakes, 19-Inch Wheels, Aluminum Pedals, Leather Heated Seats, LSD, and Sport Suspension. The one thing it doesnt have is the Navi which is supposed to come later this year.

Then there's the price. You could get the 3.8 Track for $31,000 or the IS350 for $42,725 and that's with Tech Package.

Right now in your position I'd get the IS350. DD material. I'd think the Genesis is geared more towards racing the crud out of it on the track and abusing it.
