You have a PS3 yet?
If you have any money left over, go out and buy one.
The four days will fly by. I beleive one of the racing games has a Viper in it. Get some practice.
Hmm - interesting. The only Gen II Viper in Forza 2 is the GTS ACR. Now the ACR only adds about 10hp, and adds some suspension upgrades. So I took the ACR, and "tuned" it until the horsepower was pretty close - 516 hp (mine has 512) and 561 lb-ft of torque (mine has 565.) I added sway bars as my car has, and top-notch brakes. I turned off traction control and ABS, and took it for a digital spin.
My analysis is this - these games are horribly unrealistic!! I could get the tires to spin, but they would quickly grab and hold. I could not maintain the spin into second gear. At even 35 miles an hour, I couldn't break the tires loose, and though I could lock up the tires, I only had to slightly let up on the "pedal" to regain control. The car would oversteer tremendously while braking into turns - a problem I'm not sure the Viper actually has. In general though it was quite easy to drive, as I'm sure the real thing... ...won't be.
So though it was a good idea, I'm taking my own "feedback" with a grain of salt.
It was fun, though, and certainly helped pass the time.
