The data indicates that virtually all BMW 3 Series (2005-12) 330i 4-door Saloon 3.0 M Sport Auto vehicles are equipped with a 2996 cc engine, accounting for 98.2% of the sample, with a small minority (1.8%) having a 3000 cc engine. Additionally, all vehicles in the sample use petrol as their primary fuel type. This suggests that the vast majority of this model variant features a 3.0-litre petrol engine, reflecting a consistent engine specification across the population.
