Take it slow and easy on that credit card. If you overdue it, the wife will always blame it on the bird.
Take it slow, and allow her to be seen in the bird around town as you work through the various car issues. She will definitely notice everyone is looking at her (or the car) as you make your way about town, and she will graciously enjoy the positive attention.
If you don't keep it positive, the wife could turn to never liking the bird due to money matters. The FGF Bird is one of the sexiest cars ever made, and people notice it immediately. Your wife will probably enjoy the attention.
