The best advice I can give you Pickles is show your parents you care!! I know that you must tell them all the time how much you want it, but that is not what I mean. Show them how much you want it by helping out around the house and outside in the yard. Get a job, work a little more, this will show them that you really do want this quad and that you understand the value of a dollar. I am not going to guarantee this will work, but I do know that it can not hurt! Good luck on getting your R, just be patient!! B)
