📚 Vehicle History

Daewoo Automotive:

Daewoo Motor Company was a South Korean manufacturer, part of the Daewoo Group. Known for producing a range of passenger cars, often based on designs licensed from other manufacturers (e.g., Italdesign, Porsche, Suzuki) or their own developments. The company faced financial difficulties in the late 1990s and early 2000s, eventually leading to its acquisition by General Motors.

Matiz Development:

The Daewoo Matiz was originally conceived by Italdesign Giugiaro as a city car concept. It was first introduced in 1997 as the Daewoo Matiz (M100). The 2003 model represents an evolution, often referred to as the M150, featuring updated styling (e.g., redesigned front and rear fascias, headlights, and grille) compared to the original M100.

Production Period:

The M100 generation was produced from 1997 to 2005. The M150 facelift was introduced around 2000/2001 and continued through the 2003 model year and beyond until the M200 generation. The Matiz was also produced and sold under other brands, notably as the Chevrolet Matiz in many markets after GM's acquisition.

🏆 Awards & Recognition

Safety Awards:

As mentioned, received a 2-star Euro NCAP rating, indicating it met minimum safety standards of the time but was not a class leader in occupant protection.

Market Reception:

Generally well-received in its segment for affordability and urban usability, though perceived build quality and refinement were often points of comparison against European and Japanese competitors.
