Sketch #1 is an expensive yet comfortable car with strong air conditioning and automatic controls. However, it requires special high-cost gasoline and can reach speeds of 950 km/hr, making it suited only for desert driving. Sketch #2 is a colorful yet normal-speed car without air conditioning but with much technology. However, it consumes a lot of diesel fuel and has delicate wheels. Sketch #3 is an affordable yet large two-floor car for both adults and kids, but comes in just one color and can overheat from its solar panels.
