In fairness, it could well be. I sit just outside the financial whizzyness of London, where there may be higher percentages of non-enthusiast buyers.
Not a case of "it could well be", sadly it is a fact in London and the more affluent suburbs where the price of properties (anything under a £million+ is becoming a rareity), dictates that you must also have the most prestigious cars that money can buy and they are certainly not petrolheads, just moneyheads.
And it seems the Chelsea Tractor image is a must have for the +1s doing the school runs - again image is way more important than whether they are necessary.
