Getting our own car....

Come July this year, we will have to either purchase a car or continue to lease a car. I've been calculating that perhaps buying a car would work out to be more economical. The only problem of owning our own car is the cost of maintenance and the exorbitant car insurances. I wonder if there is a cheap car insurance that I can sign on. Ok. Not any Tom Dick and Harry insurances, but one that is reliable, economical and provides the best coverage. Any good companies to recommend?
