Filing history and where it was sold
Goldenvale filed one certificate under this family, for model year 2008, sold as 50-state, California included.
The vehicle itself is recorded as built by the same company, UNIQUE INDUSTRIAL & TRADING CO LTD in CHINA — engine and chassis from one source.
Certified emission levels: CO 12.8, HC+NOx 1.6 g/km.
Other records carrying the same engine code
Goldenvale certified an engine with this code under one other family number — the same engine filed again in another year, or in an off-road and a street version:
- 7GLDX0.12NFG (2007)
A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
