The Annual International "Car Week/Grand Concourse" in Monterey/Carmel/Pebble Beach, CA is held every August and is a beautiful place to visit, and to see a good variety of makes, models, and vintages including some beautiful Cats:

Something for everyone and every budget. Lots of events including (free) casual street/park and (not free) curated shows, exclusive evening affairs/dinners (some with admission prices that make politicians' fundraisers look respectable), auctions (including vintage), and races at Arroyo Seco where the roar of McLaren's and others echo through the canyons.

Actually, just driving around during that week is a show and there are other events alongside worthy of enjoying.
Attended an unrelated neighborhood event in Carmel Valley that week that drew about 80 beautiful cars and saw one of my fave Cats: '56 XK140 rag top in Cotswald Blue in mint condition. Truly a beauty!

Driving the Big Sur Coast in a well tuned Cat is an epic experience.
