This is apparently a hard set to find. In fact, I went to the Lego Store at the Walden Galleria just to buy this set … and they had sold out 10 minutes prior to my arrival! Darn.
Fortunately, the guy at the Lego Store told me that they would be getting more on their next shipment a day or two later. And they did!
I love the way this set looks and it perfectly compliments the larger version of the Lego DeLorean (actually both are titled the Lego Time Machine.)
