My Daily Driver is a 1999 Porsche Boxster!
It's fun to drive, gets about the same mileage an your average V8 american sedan, looks great, and has been more reliable than I expected. It also has incredible storage space, especially with a RTS. It is also winter capable, and has never let me down in the snow, or hauling my skis up a mountain.
(I know you asked about non Boxster DD's, but I couldn't resist because the Boxster is such a fantastic DD. Especially because Boxster's that are driven often are less likely to have problems.)
