Simon..From what I can see,that may be a bit myth based.. We just bought a new motor for our business for around 600K... In Aussie,the same vehicle cost 20,000 Dollars.. Nearly 900K!Decent car......very expensive there, I know.
Well worth checking the prices of vehicles you like online and then checking for price comparison..
You might be surprised..
My step father had a look at at a few SUV`s and pickups here and says they are far cheaper than the UK.
