The short answer
How they differ
Both build in the US, but at different scales and models. Monarch builds a single-owner bespoke commission for one buyer. ECD, based in Kissimmee, Florida, is the segment's largest builder, with more than 600 cars, an online configurator, built-for-inventory vehicles, financing, and an EV option.
Where Monarch is the stronger fit
Monarch suits a buyer who wants a true one-off: ground-up from its own donor, modern GM LS3 or LT1 V8, fully open specification, build documentation, and a 12-month warranty.
Where ECD may fit better
A buyer who wants an online configurator, financing, faster availability through inventory cars, or an electric Defender may prefer ECD's scale.
