Good news everyone(farnsworth LOL) I finally got the ZR-1 last night around day 127. Gotta say, its the best Corvette that i have driven in all of the GT's. Its fast, and has good handling. Only issue is that on test track with S difficulty, the veyron's that i am always put up against are impossible to pass. The ZR-1 has a top speed of 235MPH. the Veyrons have a top speed of 253MPH. So its impossible to win.
