i dont think showing him cars will change his mind one bit... giving him a ride in a car that can handle and stop might infuse him the respect you are looking for from him... but if he is into pro street thats his thing... some people thing 4 rotor mazdas are the coolest thing ever.. others want carbonroof Civics and some think cars should be banned if they arent electric.. (i mean Jay Leno spends tens of millions on steam powered cars
)
if i were you id shrug it off and open your invisible bs-umbrella when he talks smack about "the other cars" and retrete to your mental happy place instead of letting it get to you
and yeah i have a friend who just dont get PT... even after a ride in the malibu.. he thinks prostreet and 4x4 is the cooest thing ever.. and nothing but a bmw can handle... how do you argue with that?
