Yeah what shits me is the ones who change flavours. A mate of mine was hell bent on his Nissan Navara (Frontier in the US) and spent years telling everyone there wasn't a better 4wd on the market and Toyota's were the shittiest 4wd ever. Then he replaced it with an Isuzu and suddenly the Nissan was crap, then he replaced the Isuzu with a bloody Toyota and now everything else is shit. It's funny to watch bit it does get boring.
I have a friend just like that I think. Whatever he has is the best of whatever it is. Until they get the next thing and then that's the best. It's funny and infuriating at the same time lol.
