Show us what you want, but can't have.
I can't just choose one, so I've narrowed it down to three! (and resisted putting any beautiful yet unattainable women in the post!) So here are three things I can't have right now because, well, they're rather pricey...
A Gretsch White Falcon. Now that is a guitar. If Bernini made guitars, he'd have wrought this out of stone and places it in the lap of St Theresa, and then we'd all have understood her ecstasy. It's a total masterpiece, sadly the picture doesn't near do it justice.
A 1957 Maserati 450 S. Only Ten were ever made. I like Ferrari 250 GTO's too, but I really love Maserati. I'd lose the decals though, apart from the black number in white, and have it just for cruising.
A Trip to St. Petersburg. Yeah, they'll tell you it's affordable. Not when you make an itinerary like the one I priced out it ain't. And I have to go during the White Nights, because that must be pretty amazing, and I could go to the Mariinsky during the festival.
