If you had asked me after my first visit how I felt, they would have awarded them two stars. But, as a particularly difficult customer, I feel that they have bent over backwards to address my concerns. On one occasion I had to wait for parts and missed a service deal, but they honoured the deal and gave me the discount. Bottom line is that they're a business and they are going to try and upsell you- just be friendly and firm and they will back down.
