Our 2000 beetle will drain down enough to not start the car if not driven for 5 to 6 weeks.
Any modern car will do this. The alarm system and whatever other electronics will cause a drain of around 50 milliamps all the time. This is 1/20 amp so over 24 hours it will drain around 1 amp-hour from the battery. Automotive batteries have around 40-60 amp-hours capacity, so 40-60 days will drain it completely. Not starting after 5 weeks of sitting would be completely normal.
