Well thats what i do actually , i am in the car industry.I'm not sure why you think that everyone in HLTV is below 14 but anyways. All i could suggest him is pick up some reliable car , but not something that will not come out of the service. This is my personal preference of course , because you know , we have a lot of work to do, instead of dealing with our cars all the time. Since a second hand is never certain, at least knowing that it chooses a suitable engine/gearbox for a certain model (A4 B8 is one good example that multitronic is not reliable and many people have troubles with it). The "reliable" thing is not only about us mechanics but for any car owner , im pretty sure that nobody likes to visit service regularly.But as you said better to consult with a familiar / family mechanic who can point it in the right direction.
