Correct Topology??

I just wanting some advice on how to make the car smoother. The is like my second model I make and I’m having trouble making it smooth.

Also I want to know if the topology is correct I had lots of trouble with that too. I not sure it flows right.

Any advice would be appreciated here is my model thus far.

there are three pics in the set. THAnks

I think the model looks great! As far as advice goes, I’m far from qualified to be giving any.

on models that are not supposed to deform topology doesn’t matter that much. If you have problems getting areas smooth the best you can do is trying to reduce your vertex count in these areas to as few vertices as possible to still being able to support the shape to the degree you need and then evenly spread these vertices.
And then of course let your loops flow in directions that support the shape.
