My (4 year old) daughter has her heart set on an electric ride on car for Christmas. I have been doing some research and the seams to be 2 basic choices to make. Going for an official licensed car i.e. Audi, BMW, Mercedes brand or a generic type and choosing between 6v and 12v. Now I am not going to get the licensed one as they are too expensive and will go for a 12v model as the description says they can go over grass so would be able to be used in my back garden. Does anyone have any experience of these cars? Any models or retailers to avoid? I will be ordering this tonight or tomorrow so any advice will be welcome. I am looking to spend up to about £150 and would want it to last her a few years.
