My first motor vehicle at the age of 16 was a Honda C50. This motorcycle, the worlds biggest selling motor vehicle, was the foundation of Hondas reputation. Here is an extract from the Wikipedia entry-
"The Super Cub sold poorly at first, owing mainly to the recession in Japan, and then three months after the 1958 launch when customer complaints began rolling in about slipping clutches. Honda salesmen and factory workers gave up holidays to repair the affected Super Cubs, visiting each customer in person."
Take note Honda.Thats how you built a good reputation. Its still applies . To paraphrase the words of the Roman General Pompey "Speak not of delays and payment. We have Forums"
