Saab 900 NG / 9-3 OG
The New Generation (NG) Saab 900 and the subsequent Original Generation (OG) 9-3 marked Saab's transition under General Motors ownership, utilizing the Vauxhall Cavalier/Vectra platform. While purists lamented the loss of the classic bespoke architecture, these models brought Saab into the modern era, offering excellent safety features, strong turbocharged engines, and practical hatchback or convertible body styles. In the UK, they are affordable entry-level modern classics. Reliability is generally good, though the B204/B205 engines are susceptible to oil sludge if not serviced with fully synthetic oil. They suit buyers looking for a safe, comfortable, and quirky daily driver or weekend convertible.
