that's hard to read. when i was 17 i had a supercharged e30 for a short while, and i was so mad when my mom pretty much forced me to sell it, but after like 2 years i got over it and understood why she made me, but i will say, that parents should not under no circumstances give a child a car with no more than 200hp. it's not too slow and it's not 2 fast. 500hp is ridiculously fast in person, and no matter how you look at it, it's fast.
also, i would say speed3 if you plan on racing or autoxin, and speed6 for a daily driver. speed3 would be cheaper than speed6 in the long run.
