I am 36 and have just ordered the FR TDI in Black Magic.
Much like the Golf TDI this car will replace, I feel it is just right in terms of the car I feel I ought to be driving, the correct "image" and also it is far and away the best of a series of comparable cars I have test driven.
I tried a Ford Focus and Renault Megane, both were no good anyway but I must admit the image thing did come into the equation.
I have a 4 month old baby and my wife drives a Ford Puma (she is 33). We both feel that as long as we can fit the appropriate quick-release car seat in a car and it will accept a folded up pushchair, a little suitcase and a few Tesco carrier bags, why on earth would we sell our souls, give up the reason for living, and get one of those caravan sized bricks that people think you have to have when a child comes along.
I don't think my forthcoming Leon FR is either too "young" or "old" for my age!
