Hmm, strange that they didn't also call it a german spec
Out of my experience the terminology used means this:
Mint = The engine doesn't leak oil, into the driver's compartment.
Immaculate = It looks good for a 20 year old car (its less than 10 years old)
Stock standard (factory original) = There is at least one part on the car that was on it when it left the factory or 2. the stock stuff was glued back on after an attempt to fit aftermarket parts resulted in a large number of plastic clips to be broken or 3. No holes were drilled in the boot lid to a fit a spoiler that he got from a friend with a scooby (the guy in the scooby got rid of it because it was to big)
Old lady/ lady driver = The clutch has been burned more times than the furnaces at a steel works.
German spec = The owner heard or read somewhere that Germany is awesome.
Full house = It has no real extras
Recently had a very comprehensive service at the dealers = The problem where the engine would catch fire has pretty much been sorted out.
