Sorry to report I buy based on subject first and foremost.
BUT,,,,,,,, I HIGHLY prefer to avoid 1/24th scale anything. Unless I cant get the subject I'm after in any other form . For example, I searched out and bought Johan 1970 Roadrunners and GTX kits as I really don't like the Monogram versions of said car.
Therefor about the only 1.24th scale kits I own are the early 30s cars, They are all either Monogram or Heller.
