I had an '88 targa with stock AC (some of the best AC for pre-964 911s) for about 5 years. THere was one period of about 9 months where the AC was inop.

In the summer in Houston, having the top off of a targa is not an improvement over having the windows down. Having the sun beat on you down here sucks.

Upgraded AC sounds like a plan. The trip sounds like a blast/adventure and would hopefully be a great chapter with the daughter.

Hit any and all preventative maintenance that you can imagine and some that you don't, but the guys here mention. It might not be a bad time for new tires, new wipers, new consumables. Maybe adjust the valves which would include new valve cover gaskets, all filters. Flush the brake fluid, etc....

Good luck and enjoy!
