On the topic of people, when looking for used cars, looking for the most loaded cars, I bought a used Audi S4 about 4 years ago, and at that time finding one in any of the colours I'd prefer and with a manual box was VERY hard, so I settled on a very new with really low mileage and basically "poverty level" as far as factory fitted options are concerned, and I'm happy with that! On the Audi B8 S4 forum, most potential buyer claim to put "sports diff" and "super sport seats" well above general condition, age or mileage - which does seem a bit strange to me.
On the subject of different levels of Central Electrics controllers, the aim, on the Polo site, seems to be to get hold of a T5 or the Amorak controller as they have a lot more I/P and O/P ports so lots more options can be fitted.
