revise descriptive title

[babybird150150]

Hi,

I listed a collector car and would like the model to be searchable, but it won't allow me to revise searchable items such as descriptive title. The model is only  listed as other. Any suggestions? I don't think the right people are finding my item, and I've had many comments from buyers that my car was hard to find. Please respond fast, 4 days left. Thanks in advance! - Roger
