The trouble with buying aircraft is that you THINK you know what you want until you get it home and then you realise it wasn't at all the right thing.
It happened to me several times and I know it has happened to others.
If people apply the same principle to buying a plane that they do to buying a car (ie 75% of the factor is how it looks) then they will be sorely disappointed.
To finish my point, I know of at least 5 people who have owned more than 5 planes in their lifetime and they all own C150's now and wouldn't sell them for the world!!
Food for thought.....
