The idea is good but the execution doesn't do it justice. It doesn't quite look enough like a car yet. I don't get the giant '@' symbol in the middle. The gradient isn't nice. I'd suggest making the logo and type green and putting them on a white background (if you really want to use the green). I can see the ability is there though, just needs some more refinement :)

House on wheels with a big '@' and pretty badly executed.
I cannot judge an idea because there is no brief or description (as far as I am concerned it could be a moving hot dog stand taking orders by e-mail, who knows) but judging by everything else, this is not going to work.

... and never use gradients... Try to design logo's in 1 or 2 colours

First of all, you don't need to paint a house and/or a car to let everybody know that you are in the real state and auto seals business, let alone a mutant of a house and a car that makes me think that you sell winnebagos.

You sell houses AND cars, not houses on cars.

I'm not going to ask you about the "@". Just put it away. In 2011 everybody knows what an email is.
