The BMW X3 (2005-10) 5DR SUV 2.0D 150 M SPORT 6SPD is a premium compact SUV with five doors, a raised driving position and useful family space. It offered an alternative to ordinary hatchbacks, combining BMW’s sporty image with practical, all-weather capability in a manageable size for everyday UK driving and commuting. Its 150hp diesel suits commuting, family trips and longer journeys; M Sport trim gives it a purposeful look and sportier feel. Compared with mainstream SUVs such as the Honda CR-V, it has a more upmarket badge and engaging character, though used examples can cost more to maintain than simpler rivals. mycarcheck.com has recorded 1,257 checks across 508 distinct VINs, a substantial sample.
