This game is really fun, nice and simple, but I wish there was a magic for the Disenchantment of items. E.g You have a helmet that gives +XP 8% and +Defense of 3, you could use the spell to break the helmet down into 1 component (to keep it balanced) and get that component in I guess a raw "essence" which isn't an artifact (unless you make it become one).
From what iv'e gathered here is what each part does:
Boost - Gives extra fuel basically
Weapon - Shoots zombies before you hit them
Fuel - How far you can go before you stop
Wheels - Acceleration/Traction (How quick you speed up)
Transmissions - Strength (How hard your wheels can push your car)
Engines - Your maximum speed limit (How fast you can go)

Level 5 stats, A virus that can shoot in 6 Directions and Penetrate Walls but Can't fully infect Mogadishu without dying instantly... that's a little unfair considering its the 4th stage in Africa...
