You probably should avoid aggravating yourself further and wasting time.
First, there is a reason that all 50 States have some form of a Lemon Law. Laws are passed to remedy problems which have become widespread. However, the mere fact that there is a Lemon Law does not mean that you will be treated differently if you represent yourself. It still costs a manufacturer less to drag it out with an unrepresented consumer and hope you will either go away or take little or nothing, than it would cost them to buy back everyone’s vehicle who made a complaint.
Second, if you fail, you will have wasted precious time if you then have to hire an attorney.
Third, the right law Firm does NOT charge YOU an hourly attorney’s fee! By being represented by the right law Firm you lend legitimacy to your case. If you select a law office that limits their practice to consumer law, the manufacturer will most likely already know your law Firm. If your law Firm has successfully handled multiple Lemon Law claims, the manufacturer will know that you have someone on your side who knows what they are doing. Furthermore, if the manufacturer knows that if you do not get what you want, you have the ability and the will to file a lawsuit, you will be treated with more respect. This is because it costs the manufacturer money just to defend a lawsuit (starting from the moment you file the Complaint) as they have to send it to a qualified local law Firm to defend it.
