C 70 / Shopping experience

Hello together, on Thursday I (and my wife) get a new C 70 convertible. I (we are happy!) After I was always very happy with the XC90 D5, EZ 2.2004 and I sold our “second car” Passat TDI year 1998 after more than 200.00 Km on eBay, it should be a convertible. I looked at various cars. BMW 330CI (also three-year-old too expensive). MINNI (super saleswoman but in leasing more expensive than the C 70. -with wholesale agreement) VW EOS – the seller called – although I signaled concrete purchase intentions for today only after three days. Pretence “technical problems with the PC” etc. Basically, a purchase decision depends heavily on the seller – and therefore I write these lines- I would be interested beyond the car what experiences you have made when buying your car. I mean some people really don’t need it and that bothers me. With the new Volvo dealer from Delmenhorst, who here in Oldenburg I was honest to say hello.
