Porsche dealerships in London are notoriously miserly with test drives. Usually, after they have photocopied your drivers licence and made you sign a form where you agree to a GBP5000 excess on their insurance , they take you on a test drive where they drive for the first 5 minutes and then switch places with you.

Usually test drives last no more than 30 minutes. Sometimes, one can persuade them to allow an extended test drive of about 1 hour.

How refreshing when I looked at my post yesterday. Porsche Centre Mayfair wrote to me offering a 24 hour test drive in either a 997 Carrera 2 Tiptronic S Coupe or a 997 Carrera 4S Tiptronic S Cabriolet.

I've never come across a 24 hour test drive in London before. I know dealerships abroad are much more generous especially with their regular customers.
