The DB9 has had a lot of reported problems. If you want my opinion, stick with the 55. I've not had one problem to date.

The most reported problem I have seen is the length of the waiting list. If there were quality problems, the press would have jumped on them...

Dunno. On real exotics technical/quality problems are tolerated easier I think. The emotion is far more important.

This in contrast to Mercedes-Benz (et.al.), that has a real hard time fighting against its own reliable image from days-gone-by.
