Although it occupies a decidedly different place in its market, Kirby seems to take a 'VW Beetle' approach to model development; that is, more evolutionary than revolutionary. The present Avalir's design is not all that different from that of the G3, which was unveiled almost a quarter century ago. There have been a lot of subtle improvements over that time, many of which can be applied to a G3, but the design is fundamentally the same. That's definitely a hallmark of a successful design but it certainly makes it difficult for Kirby to compete against itself as the second hand market is now saturated with machines highly similar to the Avalir, priced at pennies on the dollar, compared with the newest model.
