Lower Rates

My wife and I are over 65,have had no accidents,speeding or other tickets in several years,have 4 fairly late model cars,drive fewer than 20 miles a day and park in a garage. We also live outside the limits of a small town(30,000). We live on a dead end road and have our homeowners insurance with 21st century. I feel that we are paying more than we should for our auto insurance. We have been with 21st century for about 7 years. I like the service we have asked for from the company. I will be reviewing  this  before renewal in early March and have read about plans that offer deep discounts for customers with our demographics. Can you help me stay with 21st and still realize a more acceptable premium?
