I have no problem with CG- they are good as long as you understand their biz model and use a bit of common sense i.e. do your own background on a specific models SH issues and grumbles and be aware of issues that may crop up in the near future. Most of their stuff is repmobile or mobility as opposed to one careful lady owner, but thats not a bad thing sometimes The hassle of the purchase and subsequent upselling is a pain, but if you dont need it, then just be resolute and dont go for it.I prefer to view/sit/try lots of different models of the same class for comparison purposes - we ended up buying soemthing much more expensive that what we originally aimed for after a day of back to back comparision - soemthing we would not have done at a a dealer probably. The DPF issue isnt their fault - I would view a DPF as a consumable, like brakes/ tyres etc - its something you need to take into account when viewing a late model diesel - maybe an independent AA/RAC full check would have hightlighted this. We made a risk based decsison re the warranty and it has worked out OK a year later - warranties dont cover consumables and the chances of a major mechanical issue with a modern car is pretty low these days. They took our then current tank in PX and gave us a market price, surprising as it has a major/terminal E-Throttle box issue that an independednt dealer would have picked up immediately and rejected it. They bung the cheap PX cars straight to auction on a sold as seen basis. The stock moves very quickly, so what you may see in Autotrader probabaly isnt representive of their current stock- the finance differential is a non issue, so not sure where that came from. As long as you do your background, get a parkers guide and are prepared to spend a day or two in the shithole of white city, then CG is Good. if you want bespoke service @ 10% more , then go to your local dealer I spose.
