I think it's two issues.
Buyers expecting a showroom perfect 10+ year old car, with full MB service record, whilst paying under value.
They exist, but at a premium.
And poker playing sellers.
They get that the above buyer exists and try to get the premium price for an average car.
Viewing a shiney car, on a sunny day without THOROUGH research makes it easy to buy a lemon.
Exactly what we did.
Ending up paying even more as we work through the issues on a car we couldn't have honestly sold on.
now, slowly we are getting to a point where the car is more like what we thought we'd bought.
So no point in selling a 'sorted' car.
Homework before buying.
Review the threads for the model and spec of choice.
Read the buying guide:- https://www.slkworld.com/general-disc...checklist.html
Get the VIN and use Daves' (dbgrn) link previous.
Not all sellers are devious.
But if we buyers get smarter before we buy we can help put them out of business with luck.
