This was really a top-notch effort. The manner in which this tale was presented brought forth a vision of everything: the action, the emotion and disposition.

Now for my complaints...

She was, this made him blush more.

This should have been made into two sentences and maybe expanded on a bit. Just a touch would have increased the feel of the moment drastically.

She waited calmly leaning in her old jeans against the back of her blue Honda, she made no move to get her papers.

This was awkward and you have too many "she's" involved. Try it like this and it'll flow better: "She waited calmly leaning in her old jeans against the back of her blue Honda, making no move to get her papers."

He sat in the jag and reached into the glove box,

Get rid of "jag" and replaced it with "Jaguar". Narration is generally not the proper place for slang.

He came back with a pen and a little case containing his car's pedigree, and his personal info.

Good use of words, here: "the car's pedigree". I really liked that.

He felt sad, he wanted to give her his number, he had written it next to the insurance numbers. "Are you sure?"

Again, too much use of a pronoun. get rid of the second "he".

He felt sad, he wanted to give her his number, having written it next to the insurance numbers. "Are you sure?"

You might have even wished to expand the sentence, giving a little more to how much he wanted her to have his number. It would have provided a little more to the moment.

He stood lost; he looked at her for a second too long.

This moment calls for a bit of a more poetic manner. Also, I would have eliminated the semi-colon and gone with something more like this: He stood lost, his gaze resting on her a moment too long.

She watched his eyes with a knowing smile on her face, she could see his thoughts racing.

Again, you overused the pronoun "she". I would have eliminated "she could see his thoughts racing" and replaced with with "knowing his thoughts were racing."

She looked him deep in the eye this time, "Why?"

It would have aided this moment greatly had you offered a description of his eyes or what she saw dwelling within.

"You are not average. Most people would take a guy like me and a tap on the bumper and turn it into a check. There is something different about you. Please, give me your number."

This is the only part of the entire story that bothered me. It didn't seem to be in tune with the rest of the story or what he was really feeling. Sure, he was glad she wasn't interested in cleaning him out, but that isn't why he wanted to call her. I wanted something more out of this and was let down a bit.

All nit-picking aside, I really enjoyed this little tale and I can see you've a solid knack for presenting a proper mood.
