So, one of my ongoing theories is that people with huge, honkin', gas-guzzling, environment-raping SUVs are compensating for having small penises by buying oversized/overpowered vehicles. This is an informal, ANONYMOUS poll, so if you admit to having a small penis, nobody will ever know.
For the sake of the size question:
-- Small is under 5".
-- Regular is 5"-8".
-- Large is over 8".
