Three of my Omegas were first registered to Vauxhall Fleet Management, at Sale, Cheshire; as were most vehicles with the reg KV, KM etc. They often just had 'Vauxhall' on their number plates, instead of a supplying dealer. It was one way of providing a new car to Vauxhall employees at a lower monthly cost without the initial deposit usually required. The benefits were a new vehicle at regular intervals, but it was also a source of 'nearly new, low mileage' vehicles that were made available direct to dealers, and then through Vauxhall closed sales at auction again primarily for dealers. It was also a way of Vauxhall boosting new vehicle registration figures.
All manufacturers do it - pre registering vehicles, making vehicles available on a company short term lease scheme for employees which then provides a source for nearly new vehicles 'at great savings!', or so they claimed.
Although the sales / registration figures for Omegas were low in comparison to other models, it makes you wonder the what the sales figures would have actually been had the numbers of Omegas had not been initially registered this way......
