Have a think which cars have "7" in the model name, for example, the BMW 7-Series, the Peugeot 207, etc, etc. then compare the badges... one is bound to strike your fancy.
Then it's just a matter of going to your local dealer (for that make/model), or looking on eBay. You might needs to make some slight modifications, if the letters/numbers are stuck together for example, but that's how I'd go about doing it anyway.
