Should I sell my 2002 Honda Civic (manual) and buy my parents' 2007 Hyundai Elantra (automatic)?

We're only bringing one car down to California, and Dave can't drive stick shift because of his leg. Logically, it'd make a lot more sense to sell the Honda and get a car that both of us can drive...

But selling my Honda (whose name is Greta, by the way), my chariot of 10 years, feels akin to getting rid of the family dog.

Any suggestions?
