Twenty years ago, in December 1996, Brooks auctioned a nice original Maserati 3500 GT Spider for £29.000. In February 2015 Artcurial sold one in similar condition for £620.000. Nevertheless, this model seems relatively inexpensive. Why, you may ask, is the Maserati 3500 GT/GTI Spider such an interesting car? And what is today’s price level of the Spider compared with those of other open-top sports cars from the same era?
