I've been married 25 years and one thing I understand is to keep the wife happy. If your wife is a kind enough soul to agree to help you secure a new 2015 Mustang, and all that she requests is for you to consider her desire for a convertible, the GET THE CONVERTIBLE!! Your wife will then take notice that you considered her feelings, when the time comes for "modding" she'll more than likely say go for it!
Use the Force!
