I'm looking for a vehicle that combines upgraded performance with enhanced comfort. It should be designed to accommodate four people and have a powerful motor with a specification of around 6.3 kW. Additionally, I need it to reach a maximum speed of 30 km/h. Please provide detailed information on the available options that meet these criteria. I'm particularly interested in performance features, comfort enhancements, and any customization opportunities. A quick response with pricing and availability would be greatly appreciated!
