Thank you Simon. Fujimi has issued several of their Porsche 911 kits as curbsides with the bottom half of the engine molded in-place. I like to use those chassis, suspension and interior tubs to simplify the build process and add the detailed EM (Enthusiast) kit parts to them. This thread will give you an idea which kit where issued as curbside kits.
