Yes, CV is virtually monopolized by Pardee, which is unfortunate. I’ve owned two Pardee homes and had nothing but trouble with quality and with their Customer Service.
As far as shopping, there is very little in CV unless you like Von’s, Baskin-Robbins, Souplantation and Ace Hardware and that sort of thing. UTC isn’t too far away.
CV is very diverse, but probably in a different way. Lots of people from Taiwan, China, India and the middle east. My daughter’s preschool is like a little UN. 20 kids in her class, and I don’t think more than 7 or 8 of them are of strictly European descent.
