@kartcompare – I should say I love your passion.
Now, while I can imagine that a lot of effort and though has gone into the site there is a lot more to be desired for primetime. IMHO, in its current form it would make a good MVP.
What I’d like to see is an ability to let users set the comparison criteria. See http://bit.ly/PJnPWw for an example. It’ll be good to also see links to the most favorable and the most critical review. The interface perhaps can be made more leaner as well.
Overall, it is well done. What matters now is your business model and how you execute on it. G’luck.
