Southern owners that have kept their car outside

[patssle]

For those that live in the south/southwest that have kept their car outside during the brutal sun and hot summers - how has it held up (interior, top, paint)?

I'm entertaining the idea of keeping the Boxster in the garage for the next 2 months as it sits outside all day at work and just completely bakes in this Texas summer of 100 degrees +. I use a window shade and keep a window cracked - but it sits in the sun from 8 am to 5 p.m. 5 days a week (garaged at home). I have an extra car (loaded Mazda 6) that I'm not sure what to do with - maybe sell. But if I can extend the cosmetic life of the Boxster (and it's currently in nearly mint condition) by keeping it out of the heat/sun - why not. I do have the intention of keeping it for a very long time.
