The second-generation Citroën C5 (internal code X7) marked a radical departure from its predecessor. Abandoning the quirky hatchback styling for a sleek, Germanic three-box sedan and a cavernous 'Tourer' estate, it aimed squarely at the premium segment. Its standout feature was the choice of suspension: standard steel springs for base models, and the legendary Hydractive III+ hydro-pneumatic suspension for higher trims, offering unmatched ride comfort. While heavy, it boasts exceptional sound insulation and cruising refinement. Reliability heavily depends on the chosen powertrain, with a stark contrast between the bulletproof 2.0 HDi and the problematic early 1.6 THP or 2.7 V6 HDi.
The Citroën C5 (X7) is one of the last true traditional Citroëns, offering a 'magic carpet' ride thanks to its Hydractive suspension. It is a phenomenal long-distance cruiser. However, buying one requires careful engine selection. Avoid the 2.7 V6 HDi, the early 1.6 THP, and the 1.6 HDi 110 at all costs. The sweet spot is undoubtedly the 2.0 HDi (140 or 163 hp) paired with the Hydractive suspension. If you find a well-maintained 2.0 HDi Exclusive, you are getting luxury-car refinement for a fraction of the price. Negotiate hard on BlueHDi models if the AdBlue tank hasn't been replaced yet.
