I think it depends on a number of variables, such as...
- do you use it for work commute
- how far is the daily commute
- traffic condition of said commute
I once owned a Boxster as my only car but I took public transit into the city for work. When I changed job that required a 60mi round trip that includes traffic, I quickly had to add an auto DD.
Good luck in your pursuit of your dream car!
