Everything works on our car, most of it just doesn't work very well.
There's a hole in the exhaust somewhere, it pops out of gear in 3rd continually, another suspension bushing has corroded, power steering is very stiff, the "power saver" mode comes on continually when the ignition is off despite the battery being fully charged and the nearside seat angle adjuster is knackered.
It's not going to be worth selling when I replace it with something reasonable.
