We are very ‘proud’ of our travel system. It is a 2016 Fit. We fold down the 60% back seat and first lay down the electric bass case flat in that area. Then we sit the upright bass on its side on top of that with the neck going between the two front seats - with bridge facing driver’s side. The amp goes behind the rear passenger, in the cargo area. That is the key to it all. Everything else packed in soft cases or garbage bags fills in the cracks.
