Buying Tips for the 2006–2008 Jaguar XK (X150)

  • ✓Check the passenger footwell for dampness; the AC drain (duckbill) often blocks, leaking water into the cabin.
  • ✓Keep the car on a battery maintainer (like a CTEK) if not driven daily to avoid "ghost" electrical errors.
  • ✓5.0 V8 models (2009+) should be checked for water pump leaks and timing chain rattle.
