Once upon a time, owning a sports car meant making a few sacrifices and having a chiropractor on speed dial. Sure, only a sucker for punishment would drive something like a Caterham Seven or Ariel Atom every day, but most modern cars are safe, reliable, comfortable and come with the kind of equipment you need for a daily commute. You just need to ensure that the boot is large enough to carry any groceries you buy on the way back from the office.
