Production1988–1990
Recorded originGermany
ClassOpen two-seat roadster
The sole automobile manufactured by Werner Herrler's Cars & Kit - Herrler and sold under the HSA marque. It replicated the Lotus Seven with aluminium and glass-reinforced-plastic bodywork and Ford Sierra mechanicals. A period catalog gave DM 23,500 for the kit and DM 49,500 for a complete car. The 1988–90 range follows the documented Cars & Kit - Herrler trading-name period and is an evidence envelope, not proof of uninterrupted annual output. Imported replicas later reworked and homologated by HSA Automobile GmbH are excluded because no HSA model names or manufacturer identity are documented for them.

No dependable production total or kit-versus-turnkey split survives.
