I would guess it's one of the new Sport Pilot ("Light Sport") certified planes. These were designed to work with the new FAA Sport Pilot license (which requires very minimal training, an automobile driver's license and no medical exam).
If that were a kit plane, it was have an "X" (for Experimental) at the front of the tail number (looks like a regular "N" to me).
The new SP planes are pretty limited in size (two seats only), speed and fuel capacity.
The point of the Sport Pilot initiative was to rein in all the "ultralight" planes. Ultralight aircraft are not regulated by the FAA and it's an open secret that many of them do not really comply with the ultralight rules (ie-max weight of 254 lbs......we have several 400 to 500 lb ultralights in my area).
The Sport Pilot deal is regulated under the FAA (but rules are not real strict). It's actually a decent compromise (in my opinion) to get more of the illegal ultralight flying placed under reasonable FAA regs.
The only problem is that the new Sport Pilot planes were supposed to be cheap. Most are actually north of $100,000 (including probably the one above).
