I have a brochure that covers my car, a 1996 1.6 K series Supersport. It mentions the K series and Vauxhall engines but not the Ford engine supersprint. However, all the variants have 14" wheels except the Superlight versions which have 13". Yes, many of the photographs show 15" wheels but each page has the comment "Please note: photographs may include options" (My car has 14" wheels)
