This is my favorite twice-weekly automotive podcast. Its 4 guys expressing their automotive opinion in a light, hilarious and very informative way. Instead of focusing on the newest supercars and specs they focus on cars with a sense of occasion, great driving dynamics and are attainable. 

Last year I attended their 2017 Costal Range Rally , 3-day rally from Carmel, CA to Ventura, CA with ~60 cars and 100 of their listeners. Most recently they have started Radwood , a 80s and 90s car show in California that has been covered by Jalopnik and many other sources. 

Enjoy!
