To get the car, you are required to get 10 Platinum Medals from doing time trials. To unlock the time trail feature you are required to be at least office level 5.
The best car everyone in the community suggests, including us, is the Matsuda Mia (Mazda Miata) which just costs around $4,500 dollars and only requires you to have office level 2. However you will have to upgrade your Matsuda Mia to its maximum performance, which requires you to unlock the performance upgrades at office level 6.
Also special reminder, you do have to get platinum metal from several of the races on the map, not just one single race. That includes doing different amounts of laps.
The Koneg Jescool Raid is one of the best performance cars in the game, with an insane top speed of 492 km/h (305 mph) when fully upgraded. It also has insane handling and very good acceleration.
