13 3 1To reach the top speed of 240 mph in you need to be near the end of the main story and unlock cars that can potentially be upgraded to 399.I chose the Koenigsegg, which costs almost 800k credits but lets you reach the 240 mph without any upgrades. this can be obtained during the mission "The Highway Heist." just ignore the checkpoints and continue going straight along the highway. no need to purchase any vehicle.Posted by TheAnonymity on 04 Jan 18 at 02:55 Leave a comment
