The data indicates that the majority of Volvo S40 (2004-07) 1.6D SE models in the sample were manufactured in 2005, accounting for 49% of the vehicles. Vehicles from 2005 are notably more prevalent than those from 2006 (28.6%) and 2007 (22.4%). This suggests that the 2005 models are the most common in circulation within the sample, potentially due to higher production volumes or better longevity. The relatively lower proportions of newer models from 2006 and 2007 may also reflect fleet turnover or market preferences during that period.
