Yep, they are no doubt expensive. People that buy the likes of an LF-A surely have many other vehicles in their stable. The average person that has $500k to spend probably won't spend it all on one vehicle, but buy a modest vehicle and pocket/invest the rest. Someone that has millions (which is obviously who this market is targeted at) doesn't think twice about paying that kind of money for a car.
There are 2 LF-A that are coming to Ontario. I know both owners.
One of them is a bazillionaire who was a pioneer in Lasik surgeries, and has done at least 50,000 procedures. At a few thousand per surgery, you do the math. He has many supercars. The last one I saw him in was a new Bentley Continental GT.
The other owner is a young guy who is spending his inheritance/tuition/savings on an LF-A.
One in TO, one in Windsor.
