Haha, i can tell you're excited. Yes, the car has good acceleration due to 2 engines. Just be careful with the Solar roof- it is very delicate! But, why go for a 4 grade? Does the solar panel charge the batteries? I hope they are efficient tho:P
Solar panel: The photovoltaic solar panel on the roof of the Toyota Prius generates electricity that runs a cabin vent fan to cool the interior on hot, sunny days.
If that keeps the AC on, you can sleep inside on hot summer days for free!
