correct me if I'm wrong, but usually, when you buy a new car, the automatic is usually more expensive than the manual version

If you went into a Ford dealer and ordered a brand new Focus, you'd pay more if you wanted an Auto......

Therefore, the same would apply to the 2nd hand market, where automatic versions of 'mainstream' cars are rarer and therefore, more expensive. Manual versions are 10 a penny, whereas auto's are rare

don't know if the same applies to 'prestige' brands such as Mercedes, where an automatic gearboxes is deemed 'the norm' for those kinds of brands...
