Booked in for a test drive on the Thursday evening and decided to go ahead with the purchase. The process seemed to take an age and we were told that there were two customers ahead of us so it could be late in the evening before the sale was completed. We arranged to come back at 12.00 on the Friday and it was 15.30 before I left the forecourt with the car. There seemed to be poor communication and a lack of effective handovers between staff. There were periods where we were sat waiting for long periods of time not knowing who was going to be dealing with the next stage of the sale. We were told they don't have spare keys so I was only given one key and am currently waiting for the V5C to arrive so I can get one programmed at a Citroën dealership (the advice from Big Motoring World was to claim a lost key on my insurance!). Then there was the application for the V5C. I was given the V62 form to fill in and told to physically take it to the nearest post office to send it off and tax it and come back to collect the car. Not only did this seem a highly inefficient way of doing this, but when I got to the post office, the DVLA kept rejecting the application. When I rang the DVLA I was told this was because Big Motoring World hadn't changed the registered keeper, so I was unable to tax it. Eventually the branch manager got involved and it all worked out from there but it was a ridiculous experience and left me unable to recommend the company
