Recently binged all 3 series, bloody loved it. What distinguished it from other comedies I've tried recently (People Just Do Nothing, This Country and a few others) was that I wished I was part of their crew, found myself envying their relatively cosy, gentle lives.
One question mark with S3 was the bit in an early episode where the Terra Firma lot are plotting to cheat at a rally by planting their finds. Felt like that had maybe been supposed to come back later but there wasn't room. Good decision if so as the finale was bloody perfect, loved the stuff with Lance and Garfunkel morphing from shit-talking rivals into shit-talking pals
