bmw warranty

Thinking of buying a 2003 330xi. How important is it that I buy from a BMW dealer, as it would come cetified w warranty. Are the warranties full just like the ones on the original purchase (4/50,000)? Also I noticied alot more 2003 than any other year, is there a reason for this? (Problems?)

there are more '03 because leases are normally for 3 years and that's what is coming back on the lots now.

Your car comes with a 4 year 50Kmile FULL MAINTAENCE warraty. A CPO car comes with an additional 2 year 50K mile MAJOR MECHANICAL warranty. $50 deductible and just covers major components. Lower intrest rates are also available on the '03 CPO cars, most of them.
