I'm studying French again. One thing I've learned is that as 'la voiture' is feminine, so are all car makes, so la Renault, la Peugeot, la Morgan.
On that basis, must be W33 LAS.
Interestingly, gender wise, although the french car is female, so is a motor cycle and a bicycle. But, a lorry, van, tractor and a motor are all male.
