don't give up on it its always hard dealing with the teething problems of a new car but once its sorted you can rest assured knowing you've put everything right.
How do you think i used to feel when my cabby would take 5 mins solid cranking over to start on the petrol station forecourt, then when it did start the alternator belt would squeal

and everyone is walking past with look on their face as if to say "look at that old banger that won't start"
Its worth it in the end
