I put my 240Z on the market in August 2011, with the intent to buy a 911 when it sold. Started keeping track of everything offered in the Pac NW so as to be ready. The deal on the 240Z was sealed in early October. (It stayed in my garage until Halloween awaiting shipment to Norway.) Since I knew what cars were available, I was able to make a deal on the Porsche in short order, picking it up about 2 weeks after I had payment for the Z. I actually picked up the Porsche 3 days before the transporter picked up the Datsun.
So depending on how you count, I was looking for either 3 months, or 2 weeks.
