VroomVroomVroom has evolved over the last 7 years. Here's 3 screenshots I found on the wayback machine. It has obviously evolved, however the simple concept has stayed similar. The most important thing always being front and center. The first design experienced an increase in conversion when comparison technology was introduced with a search form as seen in the 2nd design. Interestingly, the 3rd design resulted in no detectable increase over the 2nd.
