Anfield, you may find the UK & Ireland Forum better suited to a question like this, though it does run in to OMNI territory to which I realise you haven't yet access.
For the record, everyone I know in London seems to drive a Golf, the graduates to a BMW 3 series, then a BMW SUV when children come along, then stays there or if very successful move up towards an Aston like
Scotland, Jag or a Maserati.
I really like the new Jag ads, they actually make you consider buying into the brand once more, after years as old me in grey leather shoes territory. Check out the Jag Range Films, great soundtrack:
