This is kind of weird. I purchased a Pontiac GTO and a Ford Mustang. As the Horsepower and RPM's stated, they looked both powerful and decent. I went to test course with a mustang, confident enough that I might be able to beat the japanese vehicles. But became disapointed when it was stuck on gear 5 and was only able to obtain the 157 mph. Then I tried the Pontiac GTO. I already knew from the start that this car was heavy and slow in acceleration. But I thought that it might make up for the flaws with pure overall speed. Again, seriously disapointed at the fact that its top speed was around the 160 mph range.
