The De Tomaso Pantera may be the most famous car the once-proud Italian automaker built, but the Pantera only came to existence after the De Tomaso Mangusta, the first road-going car De Tomaso produced in mass quantities. Don’t be fooled by that description, though, because only 401 Mangustas were built before production stopped in 1971. Finding a Mangusta in 2018 is a rare sight. Finding one that’s still in good condition is even rarer. Fortunately, there is one that’s for sale on the Streetside Classic website.
