Excellent and attentive service without being at all pushy, definitely not your standard car salesman pitch. This was very refreshing.
You should advertise to all quite publicly that you do not negotiate on price and don't do discount as it would save a lot of time and haggling from customers. That said your prices are very good thus justifying the nonnegotiable aspect.
I would be absolutely happy about recommending CG to anyone looking to purchase a new car and will, if I still live in the area use CG again myself.
