Its a promising start. As far as aligning the panels, from my experience is always a pain. I find it is easier to model the vehicle as one object and slowly separating things out.
around the chrome grill, those extruded edges right infront of the grill itself looks to be a bit exaggeragted, I’d just move the chrome grill forward a bit. if possible.
The hood seems like you slacked on it to be honest. Its not really defined enough, but some creases and extra cutloops should help you.
One time I started modeling an m3 gtr, I’ve attached a quick .blend file of my hood so you could get some ideas for edge flow and wires.
Some wires would be nice to see of your current model.
