Forgive me for sounding harsh here... but how you see that mesh going 'smoother' than the last time is beyond me. You have more edges than last time?! The more polys you have, the more difficult it will be to shape your car because you have all these extra verts to move. Think about it.

I can see exactly whats happened here. You want your model to look 'smooth' because cars are smooth, right? So lets just chuck in loads of edges. Well I can look at your model, and I can see that a lot of edges are doing near-nothing... so really its a pointless excercise having them in the first place. EVERY POLY should be there for a good reason. If you finish this at all in this state i'll be very surprised. You're trying to much too soon.

If this were me, I'd take out over 50% of the edges for now, shape it properly with what I have and complete the base mesh so that all the edges flow (not smoothly, just tidily). Once thats done I'd start bevelling edges on curves (like arches and stuff) or adding loops / splits and manually editing them (or just smooth the whole thing of course)... basically then tarting it up so I could make it look pretty for renders and all the fun stuff.
