Frails
MINI / BMW run a similar scheme here in the UK where their marketing people call about 2 to 3 weeks after the car has been purchased. A range of questions with 1-5 ratings as answers. My dealer was great and I was happy to answer with '1' to all the questions
At the end of the question and answer session they asked if I would be prepared to do a similar survey at around the 6 month point with their technical department to see how the car is fairing mechanically - no problem was my answer.
