Lesson learned on the tagline. We've killed the "doesn't suck" part. Thanks, HN!
And a note on us calling this an MVP: we've probably used that too loosely. This is more of a proof of concept to see if there's demand in this space. We believe there is, and wanted to show what we are starting with.
I don't think you've fully decided on the problem you're trying to solve though. Is it comparing my new car options across manufacturers? What are the key deciding factors for someone getting a new car? Who are your customers? Who _aren't_ your customers?
At this point, what you've built is providing no insight into any of those questions for you, except that what you've got so far is not the product for the HN market. :)
I'd focus on those before going further down this road, but that's just one man's unsolicited opinion. I am fairly involved in the automotive industry, however, so I've got some insight.
