I still don't understand your point #4. What does 133 have anything to do with PS access to 5 or 405? IIRC, Luna Park is going to be in the area between Irvine and Alton. It takes a bit more than 5 additional minutes to get from PS to get to Irvine and Alton to access 5 or 405. Even an extra 10 minutes won't hurt your husband's commute.
Luna Park will get proximity to shopping center when the shopping center is completed, but right now Luna Park is doesn't have anything within a mile.
PS also gets access to GP, but not as easy as GP residents, perhaps. However, there is a cost for easy access to GP. Around $5000 a year in the form of MR. As I mentioned before, other Irvine communities, such as PS, EW, SG, NW, and OH, pay about $4000 a year for MR. GP residents, however pay anywhere from $7000 to $20000, based on the size of their homes. The smallest condos pay around $7000 while the huge homes in Altair pay upwards $20,000. That's MR alone. Altair homeowners pay around $50,000 a year in property taxes because their homes are assessed at more than $3M.
The only point that I agree with you is that PS is currently artificially inflated by FCB money. I'm just glad that we were able to get our home because Shea was pricing Cielo much more reasonable than New Home Company did with Olivewood. CalPac was kind of in between with Azul.
