Men's Vogue: So you're in charge of curating the collection?

Mark Reinwald: I've been with him five years. And since then I've gotten ideas of what he likes. It's a big collection. He wasn't looking for that much more. The red 1938 Alfa Romeo, and the XKS150 Jag.

MV: How do you find out about these cars? Is it mostly just word of mouth?

MR: There's many many auctions going on but most of this—the very, very high end like that Alpha Romeo—that's all word of mouth. That's a car that he had seen probably about 20 years ago and said if it ever came available… It was owned by a client of Paul Russell who passed away and Paul was helping the wife with the estate and was able to acquire the car for Ralph. But a lot of that is private—very few things do we ever buy at an auctions.

MV: Are the auctions public?

MR: They're private. We did buy the McLaren F1—the orange car—through kind of an auction. It could have been up to however many people, and when we got to the end there was only two of us left. We have our own sources—people who will call us and say, 'Hey, I got this car, are you interested?' And we kind of go from there.

MV: So what's next?

MR: When you have the best, it's hard. We're in the middle of this new building in Bedford Hills, we're concentrating on that.

MV: They're all going to go there?

MR: We'll have 'em all in one location. And then they're sent out. Like, when Ralph is in Colorado I send cars out there. You make sure everything's okay, you send out five or six cars to play with. I'm out in Montauk now, and I'm having a car picked up in Bedford today to be brought down here for him to use this weekend, and send something else back. You constantly shift the cars around.

MV: Tell me more about this new building.

MR: It's a big commercial building, 48,000 square feet. It was built as a Mercedes Benz storage place. It's gorgeous. What will be great is that we can put the cars on display and will be set up more or less like a museum, where when you walk inside it will be very stark. It'd be like a gallery, walls are white, floors black. Not a bunch of junk lying around. And then you can just pull them out and take them for a ride. There will be some up on podiums for display. But maybe about only 4 or 5 out of about 50. It'll be very nice. It'll be a completely different atmosphere.

MV: How did you arrive at this?
