there are many types of motor`s fitted to models, what your looking for here is ....
540, which i beleive is a 3 pole motor, (cheaper to produce and replace)
all 1/10 scale are restricted to 540 class motors( in compettition anyway) and hence 99.9 % of cars come with 540 motors, there are monster trucks with bigger motors .
there are various types of 540, the standard type have good all round characteristics for people starting out,their relieable,cheap and plenty of power.
very few cars ( nonne i can think of just now) come with 380 size motors.these have a smaller `can` and lower revs and less torque. used a lot in boats.
i would recomend the building of the kit, purely because you`ll know your way round it when something breaks! ( and` you will break something!) there`s maybe 3-4 evenings build in a tamiya kit, teh instructions are excellent and the parts fit very well
painting the shell is very easy also , again two or three evenings will have this done to a good standard.
2wd is fun but more awkward to learn to drive with as the rear end of the car is `skittish` ,but very rewarding when you learn to slide into and through turns.
4wd has more moving parts and , a bit more maintenance (not much mind) and handle very well, can be driven very easily but there`s still an art to drifting a 4wd car.
so don`t worry about motor as long as it`s a 540 ( as i said most are anyways) and probably 4wd would be the quickest and most fun way to get going , so the car you`ve picked is not a bad choice
