Michia, you're selling a "Buy Online" product. CTR does not sell cars. This is not a success.
Then, you follow with:
"Shoppers clicking a “Buy Online” button had a 3-4x higher conversion rate than typical online lead sources on average."
This is a vague statement, open to interpretation.
--Define 'conversion rate'.
--Define 'typical online sources' (you were specific in the table above)
To validate your product, talk about your form completion rate (i.e. bought the car online). Secondarily, for abandoned carts, talk about your lead gen rate.
p.s. This DR forum thread is filled this insights that you and your team will need to conquer.
p.p.s. It would be helpful to post a link to your product on a dealer's site.
