A friend owned a Pontiac dealership.... so I felt slightly obligated to buy into a Pontaic one time----a serious departure for someone like me who has always purchased foreign cars.
I'll cut to the chase: what really soured me on that Pontiac was the day that I found myself trying to adjust the aim of the headlights. Congratulations to the GM engineer who thought of a way to aim headlights for a total of EIGHT CENTS EACH! What a POS car. It was a 1988 Sunbird---if that matters. Once you see a manufacturer take such incredibly stupid shortcuts, you lose all faith in them forever.
Warning to anyone considering a GM product: Take a look at the headlight adjusters. If that doesn't send you running out of the showroom, you are a brave soul. Don't even get me started talking about head gaskets--between a cast iron block and an aluminum head!
I hope never to be caught dead (or alive) in another GM vehicle!
