Go back to that dealership! Casually chat while she's writing up your service appt. Ask her if she wants to grab a drink. The worst she can say is No. You win some, you lose some.
"Amy, I don't really do this but you seem really cool, do you wanna grab a drink sometime?"
Check her finger for a ring of course.
"I feel like a cocktail,(when you're picking up your car.) Hey, what time are you off? You wanna join me?"
The 2nd is more upfront and risky cause you're putting her on the spot but it could work.
Just do it or you'll regret it.
