How do you loners manage to buy a car

[MrMan]

I want to replace my used car with a less used car. My wife or son will have to go with me so I can get tgere and to drive one of the cars back.

I read complaints on here that it is hard to find a woman or make friends in whatever country the poster is in.

So my question is how do you guys buy a car if you don't live near family or have any friends?
