Yes, I've collected diecast models longer than I've built styrene models...in a lot of different scales. I've always viewed styrene models, resin, diecast,promos, etc all as interesting aspects of the same automobile replica hobby.. besides, some subjects will never be available in styrene kit form, but only as a diecast.
I don't get hung up on the built vs unbuilt aspect or diecast vs styrene, it's all the same to me...I like models and toys of cars, whether it's a 1:43rd Minichamps, 1:64th Matchbox/Hot Wheels/Tomica/Greenlight/M2/Johnny Lightning/Siku or a vintage Dinky, Corgi, Polistil, Playart, Spot-On, a 1:18th Auto Art diecast,a large scale Exoto F1 car, AMT 1:25th scale kit or promo, Revell 1:25h, Tamiya 1:20th or 1:24th, etc....
If it's a subject I'm interested in, I'm interested in having it regardless of scale or media..
