Well cause I pay my employee's salary, I know full well they can't afford to be driving anything above say... a moped. (Just kidding somewhat, I think one of the managers has a Porsche)
Generally, I don't really pay attention to what people drive, so I kinda have to limit this list to people I see more than once a month. Which is:
a) My girlfriend - drives my Toyota Camry cause it's the only automatic I've got.
b) My childhood best friend and occasional business partner - Chevrolet Corvette Z06 - 2005 model I think, has a pretty dodgy right hand drive conversion.
c) My extremely wealthy good friend (he makes the Queensland Rich list) - 2007 Daihatsu Terios.
That last one is a bit of an in-joke between my circle of car knowledgeable friends. My good friend has a large collection of rare and expensive cars including a 911 of some sort and a Ferrari TestaRossa. He was also one of the first people to be approached about importing a Zonda in Australia. However his daily driver is the Terios.
Which is good for the rest of us because his car knowledge and business knowledge are both somewhat superior to everyone elses. So when he interrupts one of our conversations pointing out a mistake we've made or giving us advice the general response is "Shut up <random insult>, you drive a Terios". We also make many jokes about how it's engine is measured in mousepower etc.
Cars around the neigbourhood are varied. Everyone in my neighbourhood is loaded...but there closest Lamborghini or Ferrari dealership is 1000km away. Plus rich people are generally old. So as a result...everyone has a Mercedes. Or a BMW. Or a Lexus. Or an R8.
Seriously, there are about 100 people on this hill - it's a gated community - and not one person doesn't have one of the cars I mentioned above. There are 7 Audi R8's on the hill, around 20 M3s ,20 C class Mercs and the M Class is a pretty common school run vehicle here.
There's some guy I don't know too well - Peter Champion - he owns all of Peter Brock's private and race vehicles (he owns a Peter Brock Museum) as well as some million dollar super exclusive muscle car (Mustang of some sort I think) I haven't seen which he keeps locked up.
