I’m popping in super-duper quickly (shouldn’t be here, but I can’t help it, haha!) just to hopefully help clarify a bit.
Bit of a spoiler about M and A though, just in case. Nothing major, but if you wanna find out about the characters as it’s revealed then don’t look! 
M is the strongest in pheromone and in most hypersense abilities.
A is strongest physically as well as being the most competant in combat.
They all have their own strengths though, even F has things they can do that the others can’t 
But more on all of that ability stuff will be revealed in Book Two…dundundun
Also, the car…I love that car, guys…hehehe!
EDIT super quick, I really have to actually work!: It was A who slammed Murphy into the bonnet of the MC’s car.
