Hatchback type car with 3 cylinder transversely mounted engine driven by front wheels, Pitman steering, and suspension on all wheels, 100% done with pieces available no later than 1994.
About this creation

Underside of vehicle showing course of exhaust pipe and trailing link suspension front and rear with decent travel at each end. Long grey elements in centre link front axle to middle of chassis to help maintain track.

Close up of front of underside of car, showing differential, drive train, crankshaft, steering with Akkerman geometry, and sturdy front wheel mountings. Black bottoms of one of the two pairs of front shock absorbers visible just above the differential.
This car only has one fixed gear as there is no room for a gearbox!

View of engine showing cylinders, part of chain drive from engine to transmission, part of one of the four front shock absorbers, and the exhaust manifold.

Cloe up of elements of Pitman type steering from right hand side. This type of steering was chosen as as most practical way to steer front wheels where front suspension is effected by trailing arms. Pitman bar is the yellow element seen hanging down from upper part of car, and this is linked to an arm which operates directly on the right hand steering arm (part of the right hand front wheel mount). A tie bar links the right hand steering arm to the left hand steering arm to steer the left front wheel with the right front wheel. Pitman bar is operated by the steering wheel through a system of gears to give steering wheel adequate mechanical advantage.

Close up of underside of rear of car showing dead beam rear suspension on trailing arms and cable operated hand brake system which is a slight advance on the handbrake system on my red Volvo. When handbrake lever is pulled, the grey elements make contact with the rear stub axles but do not actually lock it. Rubber bands on handbrake lever and at operating end of cable return system to disengaged position.

Re-working of handbrake system which now works much more smoothly - and better mechanical advantage at lever end means some friction is now introduced when handbrake is operated, plus there are no bits sticking out at the end to snag on obstacles!

Hatchback door modulated by single pneumatic unit. Peashooter exhaust. By this point I have used up all of my translucent parts on other models, so the rear lights are represented by ordinary red plates. This car is an MOT failure as there are no indicators.

Both front seats can be tilted back and forth and go forward far enough to let the kids to get in to the back seats, as this should be a two-door car.

Brilliant old-school technic at its best! The front steering and suspension is unreal - that must have taken a while to perfect. Awesome technical features, the handbrake mechanism is the work of a genius! It's a very nice-looking car, with styling that suits the pre-94 era. Well done, mate!

Thanks for the comments, yes FWD with suspension was a real challenge. This was a head scratcher and took a few prototypes before I got something that worked with suspension, drive and steering. This one always seemed somehow unfinished to me, so I've revisited it and made some changes mostly to its appearance.

FWD is an absolute PITA. 5 stars just for that!

All out of older pieces. That is amazing. I really like your functions and the little tricks you did to make them work.

Thanks all, for me the functions are the main thing and form comes as a bonus if I'm lucky, this one started as a proof of concept of a driven front axle, the Pitman steering was forced upon it when I realised there was no scope for rack and pinion if it was mounted as a trailing arm suspension (as opposed to leading link). In any case the front axle design made any sort of rack and pinion challenging at best without ball and socket joints.

Lots of cleverness here... your steering solution is very interesting and looks stronger than mine (with similar pieces). The whole thing looks very well engineered.
