If you already have taken out house insurance with one company in Maryland you may want to approach this company and ask if they have any package deals of combined car and house insurance policies. Many do, and it is often a very good way to get better premiums on your auto insurance. You should also check the local papers to see if any insurance companies are offering special deals on Maryland auto insurance, and to compare rates with other companies.  If you already have car insurance with a company another idea is to ask for any rewards they are offering. For example, if you have not made any claims for a certain number of years you may be able to negotiate lower premiums, however you will most likely need to directly ask if this is the case as it is unlikely that they will necessarily offer it.
