Wow so many paint jobs

You only are able to see two (including one for preorders) in the trial... I wouldn't expect that to remain true for the remaining 9/10 of the game.

I think the Mako is objectively better than the Nomad tbh (it had machine guns and a cannon ).  The reason we remember the Mako in a somewhat bad light, is because of those old ME1 planets.  All the tall mountains were really difficult to traverse, but I don't think it would be much better with the Nomad even with the 6 wheel drive.

I disagree.  Many of the mountains in ME1 were nearly 90 degree climbs (I'm exagerating of course, but the climbs were really steep).  After playing the 10-hour ME:A trial, I can honestly say, the Nomad would not have been able to make many of those climbs either.  There were tons of steep hills I was unable to make in the Nomad even with the 6 wheel drive activated and a bit a momentum and boost going into it.

I definitely would not call the mako "crappy", it's the ME1 planet terrains that were "crappy".

i was able to get 12 paint jobs for the nomad, the n7 and nebula paints are my fav

It is not the worst thing ever.

However when you add new mechanics to a game they should fit the game and be well done.
Driving is consuming in term of ressource and in term of gameplay it add nothing, worse it was baddly done.

That is like planet scanning, useless, a waste of ressource and somehow mandatory for other aspect of the game.

I just want a black and red nomad matching N7 color.
