For me, it was the Monogram NASCAR kits in the 80s and 90s that brought me back to the fold. I'd built (glue-bombed) a ton of kits as a kid in the 60s but forgot all about it until after divorce left me with some free time, and my passion for Winston Cup racing brought it all back. Now it's mostly replica stock builds, and this and other boards on the 'net have brought me in contact with many others sharing this crazy hobby.
