The Wii would be a Volkswagen Bug. It may not be the fastest car in the world, but it’s cheap, fun, and does what you want it to do. It handles great and looks interesting, but if you're a guy and have one then someone is eventually going to make a sexual joke at your expense.
Playstation 3 (PS3)
The PS3 would be a top-of-the-line Ferrari. It is way out of the ordinary person's price range, so it has a smaller market, but if you have enough money to get it, it has the most high-tech engine available under the hood.
Xbox 360
The Xbox 360 would be a Jeep Wrangler. 
The biggest market it appeals to are people in their teens and twenties. It is considered cooler than the Volkswagen by many but is cheaper than the Ferrari, making it a good middle-of-the-road vehicle. Upon the decision to purchase the Jeep, the future owner has the option of getting either a skimmed down version or a tricked-out off-roading version.
Unfortunately, the Jeep is notorious for easily breaking. It is top heavy, easy to flip, and the motor dies quicker than other cars.
Playstation 2 (PS2)
The Playstation 2 would be an old (but well kept) Toyota Camry. They still make new ones, but they are not the car of choice. Many of them are still on the road, and most of them look and run just fine. By far the weakest of the current cars, it is also the most affordable. Although it is a dying breed, its availability makes it more attractive to the common driver.
Nintendo DS
The Nintendo DS would be a Go-Kart. Not technically a car, but still a blast to drive around in! People love to race around in these things, but no was meant to use this as a regular car. It’s affordable and fun, and because of this it is popular.
Playstation Portable (PSP)
The PSP would be a Harley Davidson Motorcycle. 
It is more powerful than a Go-Kart, but a lot more intimidating to drive. Steering can be tricky, but once you get the hang of it, it can be pretty fun. You look cool driving it, but it is less fun than riding a Go-Kart. It can be used as an everyday car, but it was more designed for joyriding than transportation. As a bonus, there is a large fan-base of riders who love tricking out their Harley’s, and they would be more than willing to help you tweak yours too.
