If you're getting bored with the contents of your garage in Test Drive Unlimited, then you should head over to Xbox Live and check out the new beauties in the showroom. For a mere 350 points, you can bring home a Dino 246 GT, a Ferrari Challenge Stradale, a Cadillac Cien, the RUF RK Spyder, a Lamborghini Murcielago Roadster (even I've heard of that one), and the TVR T440R. Which sounds more like graphics card than a car, but I'm sure it's really cool.
The more budget-minded among you can always download the Saturn Curve for free.
