North vs South: which really is cheaper? - Final scores
The biggest saving was on the Nissan X-Trail, which produced a combined average price of £12,284, or £976 less than the same car in the South.
There were also worthwhile discounts to be had on the BMW 3 Series and the Citroen Xsara Picasso (see page six for full results).
The one car that stood out as cheaper in the South was the Vauxhall Corsa - taking an average of dealer, supermarket and private prices it proved £67 cheaper to buy down South.
Franchised dealers were predictably the most expensive places to buy a car, and all but one charged less for a car in the North.
Car supermarkets, however, were significantly cheaper, and their prices were much more consistent across the country.
