Not exactly, and here's why: although position 1 is nice, you'll still have many opportunities to convert even if your ad lands in position 2 or 3. What ad slot is the closest to the organic search results? Position 3, it's practically water-front real estate and at a cheaper price than position 1. In fact, in some of my client accounts I've set the bidding strategy to make sure our ads appear at position 3. If you bid for the #3 spot you will, on average, have lower CPCs, which means you can afford more clicks in a given budgets, which leads to more qualified customers browsing your site and eventually more car sales.
Keep in mind that position 3 has, on average, a slightly lower conversion rate compared to position 1, so this strategy is not ideal for every campaign.
Just to bring a little science into this, Google has done plenty of Eye Tracking tests on their search results page to see where user's eyes naturally look at first. Here's what they found out:
In short, I wouldn't worry too much about the #1 spot, people are still looking at you the same even at #3.
