Look both great cars i would say the lexus because your only 19 and dont need a big tough prado
though it is really what your needs are if you are in the city the lexus is the perfect car it is kind of powerful,classy and suits someone around your age
if you live in the country or transport alot of people or tow boats,caravan ect.. get the prado as they are big,powerful and can carry ALOT of things
If i was faced with this decission i would defiently buy the prado but though your only 19 a huge prado wouldnt be best idea so you really need to think about what are your needs in a car as the prado is a big and powerful and there lots of things that could happen like crashes
(most common in big 4X4 with drivers who unable to handle them propely)
though there is advantages you can do with them like going to the beach and 4 wheel driving and the prado is a very reliable car
also there is the realistic problem like what are your souroundings what if those cars are just Not enough or to much maybe a smaller 4X4 but still with classy ness like the porsche cayenne or maybe a vw touareg or a bmw X3 or X5
All up i wish you Good luck with your purchase and choose well
