Given you are in a strong negotiating position, whether you choose a PCP or buying outright really depends on your needs. Buying outright gives you the option of shopping around, while a PCP would mean a little less choice and paying a bit more overall, but also the option to change your vehicle more easily once you've paid 50 per cent of the total amount payable. From a purely financial perspective buying outright likely works out a little cheaper, but the most cost-effective option would be to buy a car that is between one and three years old to avoid the biggest chunk of depreciation.

You don't mention whether your current Volkswagen Golf R is owned outright or also on a PCP, but it would be well suited to narrow lanes being relatively compact. A MINI John Cooper Works is a little smaller still and would also be a good choice, although you might find it a little slow compared to your current Golf.
