Like others here, technical lego although I will make a specific recommendation. They used to make "test car" sets with gearboxes that work, simulated piston engines, articulated suspension and working steering.
The pinnacle, before they got too realistic body work was lego test car 8865. Once built its robust enough to play with. The engine is a little tricky and the gearbox might be puzzling to an 8 year old but its a great set for learning how a car works without being aimed completely at the grown ups market
