Baby Jogger cares alot about customer satisfaction. This should make all of us feel a little more confident in purchasing a Baby Jogger whether it be for running with their Performance series or strolling with their City Series. They care so much in fact that the strollers are manufactured in a staged assembly process which is similar to how most exotic cars are made. Using this staged assembly process is very exspensive but, it is what makes the Baby Jogger product one of the finest in the world. They undestand that there passengers are priceless and well worth the extra cost.
