Looking good! I am a super newbie when it comes to modeling, so take everything I say with a grain of salt… But if you want some sharper edges (say where the hood meets the fenders meets the body meets the doors etc.) then you might consider building each of those objects separately. That way your topology doesn’t have to match up from piece to piece and you can insert edge loops where you need them to increase sharpness without those same edge loops interfering with the rest of the car. That said, great job so far!

Hi bvz2000! Thanks for the comments. I´m still exploring best ways to do this. I will probably separate doors and panels down the line, but I try to keep everything together as long as possible. I´ll want to be able to open passenger doors anyway, so I´ll have to at some point. I actually had some promising use of ngons so far, so if I put those in wisely, I don´t have to use so many edgeloops. I´m just obsessed with keekping polycount down 
Btw, love your motorcycle
