Many shoppers prefer the later B5.5 years (2003–2005) due to updates and refinement; the best choice is the one with the most complete service history, regardless of year.

What should I check before buying a used 2003 Volkswagen Passat?

Verify service records, check for coolant leaks and stable engine temperature, scan for fault codes, confirm smooth automatic shifting, and inspect electrical functions (windows, locks, cluster) plus suspension clunks on a test drive.
