Not too keen on buying vintage, Mike. I have located a gorgeous one but it has to be discounted to even consider.
Discount is ALWAYS better than full price
, G.... I'm not a big vintage fan myself, either.
I remember some vintage shops in Manhattan, they charged outrageous prices for unwearable numbers that had given the ghost long time ago; and not just the "posh" ones, some military surplus stores were also laughably expensive.
In the 80's I used to buy vintage occasionally. Once found a great tweed German overcoat that was almost TOO WARM, even in sub freezing Detroit winters, but that was about it. Usually there were holes, or didn't fit quite right. I did what I could cause it was "the look" back then. 
Likewise, I used to mix and match new and vintage clobber in the 80s. There were some fantastic vintage shops in Sheffield in the mid-80s with clothes in the kind of styles that just weren't being made at that time and that were still in great condition; usually at good prices too.
With the plethora of clothiers available now producing new clobber in styles that I'm looking for, I don't think I'd buy vintage any longer; though if something really stood out and was in good nick, I wouldn't dismiss it completely.
