The Rubiq (built for QFC26) looks like it’s built on one of the Relay body sets, and its retro-futuristic styling brings to mind contemporary retro-styled tall wagons such as the Chrysler PT Cruiser and Chevrolet HHR.
As an aside, I could have repurposed my QFC25 entry (built on the same body set family, but in a different size) for QFC26, although its greater weight and higher costs (both upfront and long-term) scuppered that plan.
