Euro Currency Fall

So, recently, the Euro has absolutely tanked with little hope for a recovery in the near future. This is great if you fancy a break in Spain but... does anyone have any idea when this will reflect in the price of European cars in the UK. The pound buys you 10% more in the Eurozone now than it did at the beginning of the year. Has this already been reflected in European cars sold in the UK? Or is an adjustment coming soon?
