Well as far as shopping, Mission Viejo has the Shops at Mission Viejo Mall. It is a nice indoor mall with a good range of stores. Here is link to browse stores here:
Simon Property Group the street from the mall is the Kaliedoscope Courtyards. This is a sort of "mini mall"/ entertainment center on Crown Valley. It is a little geared towards teenagers though. It has the cities movie theater, a few good places to eat, and other shops.
Kaleidoscope Courtyards The city doesn't have any main single center that has everything though. Most of the stores and shopping centers are spread out through the city and there isn't one that has everything. Remember that Mission Viejo is a very spread out city set in the hills and is primarily single family residential homes. Aliso Viejo is more apartments and condos, thus having a fairly large population in a fairly small space.
Also, your car should be fine on the hills. It is not San Francisco with verticle climes. It is just slow rolling hills, that add a real nice touch to the area. If you live in Mission Viejo, you also are a member of the Lake Mission Viejo Association which is a private lake that only MV residents can use. You can swim in it and kayak and party boat. The marina has several boats available at reasonable rates.

Also, you will be fine finding a complex in Mission Viejo or Aliso Viejo for under 1,800 a month. In Mission Viejo I like to recommend Archstone Mission Viejo (
Mission Viejo Apartments at ArchstoneApartments.com). It is walking distance to the mall and shopping and has 5 minute freeway access.
Now in looking for a comple, you will find many more in Aliso Viejo. They are also a little newer. I highly recommend City Lights at Town Center. It is a beautiful complex right behind the Aliso Viejo Town Center.
Shea Apartment Communities - Northern California Apartment Communities and Southern California Apartment Communities.
Also check out San Clemente and Dana Point for complexes. These are beach front communities that could have some newer places. San Clemente has Talega which is newer and only ten minutes from the beach. If I were you, I would big the complex you like best. The cities down here are very similar and you will be happy in any (avoid San Juan though). I know I sort of wrote from a Mission Viejo perspective, but that is because I live there. All the cities down here are nice so good luck in finding a place. Again, check out City Lights, it is very nice.
