I had a similar situation when I purchased my car. When I picked it up the Sales Manager and the Sales person asked if I could give them positive feedback when the VW Customer Service called me. So I gave the dealership a real slating when VW customer service called. Even named the sales person and manager by name. If they wanted a positive feedback then they should have given a positive customer service. Sheesh.
I asked if they had any bits and pieces like a golf umbrella/keyring that they could throw in as I spent shed load of money on a new GTi however they were like no, you're going to have to pay for that. When my g/f bought her bog standard 1.6 A3 she got loads of free stuff (1 liter of top up oil, nice metal keyrings, audi umbrella, rubber mats, audi sweets in that cylindrical metal tin) plus £2k off the list price.
