I currently run 2 PSN profiles (I made a extra one for garage spaces and cause I felt like starting new characters but didn't want to delete the effort I put into my old ones.)
On profile 1 my top speed was 145 in the Turismo R. I've rearraged my garages since then and my two characters here now run Muscles, trucks, tuners/Sports Classic (shared garage) and 4 Doors. So I'm not sure if I'll top 145, that speed might stick for a while.
My top speed on profile 2 is 149, also set by the Turismo R. This one surprises me because this profile has garage set to all super cars, including a Entity, Zentorno, and Adder. Either Turismo R is faster then it's credited for, or my cars are not yet fully modded. This profile also has 4 garages, supers, high end sports, rusty mchines, and bikes.
What is your top speed(s), and what car set it?
