Solar-powered model

Hi,

I'm a newbie in electronics.. So i'd like to ask for some help
I'd like to build a solar-powered car, according to this scheme:

Link deleted by moderator.

so i've few questions..
a) is this scheme correct (it should work so - when the switch 1 is on, LED 1 turns on, and capacitor starts charging; when the capacitor is fully charged - LED 2 turns on; and when the switch 2 is on - LED3 and motors should be on)
b) which solar panel and motors should i use to get the best effect
Solar panels:
- 2x Solar panel (2V;0.2A)
- 2x Solar panel (0.5V;0.8A));
DC motors:
- 1x/2x DC Motor (3V;1.16A; 1.5W) [Link]
- 1x/2x DC Motor (6V;1.43A; 5.3W) [Link]
c) how powerful resitors & transistors, and how capacious Capacitor (car should be able to drive ~ 30 m) shoud I buy?

Don't click the link, just ends up with casino sites
