Perhaps I didn't explain the problem well. The car I drove felt as if the
first inches or so of suspension movement just wasn't 'controlled' It felt
'loose', 'unconnected'. If I was told that there were some suspension bushes
loose or missing or bolts were missing, I could understand the strange
feeling. There were no clonks and bangs which might confirm either problem.
Though the car had the 'funny' DSG gearbox the sales man said the car was an
entry level, "S".
So it looks as if I was unlucky and should avoid the dealer for not sorting
the car before using it as their demonstrator.
