You were able to purchase an extended warranty while out of the existing factory warranty??? are you currently under the CPO warranty from BMW???__C__ said:I just ordered a 4 year / unlimited mileage warranty from aaautowarranty.com for $2225 with no deductible for my 2000 M5. I have not had to make a claim yet but the backing company, Great Lakes Warranty Corporation has been in business since 1994 and is a member of the Better Business Bureau.
