I found some prices at last yr's Tampa show that were better than at the dealer's location. I wanted to compare 3 different brands that had the same floor plan, & I knew the average price for all 3, prior to going.
I was also informed by several dealers that their prices were lower because the manufacturer had given them special incentives for the show.
There were so many to compare that options began to blur. Darn, that meant we had to go a 2nd day just to take notes.
FYI: Know your state tax laws. I discovered after purchasing my last 5er out of state that KY had just passed a law for out of state purchases that required sales tax on the entire purchase price. In state purchases required tax only on the value of the difference of the trade-in & the purchase price.
