To be honest, the disco is far more economical than the last car I had and nobody bothered about 'tree hugging' all over that!
I have always had at least one big car in the household and I intend to stay that way. The Polo I have that the wife uses for nipping here and there is good fun to drive, for a short time. But I do feel really vulnerable in it! You are at wheel nut level on wagons and buses, not a nice place to be!
