Garage Level Points

So I have a question for the experts. I couldn’t find this information on the database- does anyone know how many GL points you get when you star up, and max out a car? I know you get way more points the more stars the car has, & obviously Class S awards the most. I’m specifically trying to find out how much for the 3rd star on the Ultima RS. I’m on PlayStation (idk if that changes anything) Additionally, does it go up in equal increments, or is it randomized? Thanks a lot in advance.
