You have 80 car owners in total.
24 owned station wagons.
62 owned cars which are not station wagons.
How many owned both a station wagon and a car.

24 + 62 = 86.

There are 86 cars and only 80 owners.

Assuming a maximum of 2 cars per owner, then the number of people who owned a car and a station wagon would be 6 I think.

If we have 6 people owning a car and a station wagon, then we have:

24 - 6 = 18 owned a station wagon only.
62 - 6 = 56 owned a car only.
6 owned a car and a station wagon.

That's a total of 18 + 56 + 6 = 80 people who either owned a car or a station wagon or a car and a station wagon.

That's a total of (18 * 1) + (56 * 1) + (6 * 2) cars = 18 + 56 + 12 = a total of 86 cars.
