With finance, you never really own the car. I prefer to own my own assets. Which begs the question; why spend £100k+ on a depreciating asset, which is in my opinion the amount you would need to spend to get the same sort of thrill? So take it from someone who has made that mistake one too many times, once the novelty wears off and the 'new car smell' rubs off, it promptly turns in to a horrific bottomless money pit of nonsensical and wasteful depreciation. Because let's face it, if you buy a new car, with the exception of certain exotics, that's exactly what you're getting. So if you think selling a Supra for £30k is hard, I can categorically tell you, it does not get any easier selling a used RS7 for circa £70k!
The fact of the matter is very simple, supply and demand is a universal phenomenon. it does not only apply to the US, Japan and Europe. Further, as others have said, I don't see how or why the living expenses argument would only apply to people living in the UK. So what is really causing this depression in our market? One word; uncertainty.
Sadly, this may come as a rather bitter pill for some to swallow, with the way prices are heading, these very same people have been effectively 'gentrified' and can no longer afford to buy one. As I have said previously on another thread, if people in the UK are not going to be willing to dig deeper in to their pockets, these cars, amongst other Japanese motors recently on the rise, will become scarcer and scarcer as they are bought by willing punters from abroad, until such time that we may have to eventually add an apostrophe to the word "owners" in the forum's name.
