The car manufacturing world is a very strange one, when just simple things like the Porsche 901 became the 911 because Peugeot objected to Porsche using any three digit number where the middle number was 0, asserting ownership of the naming rights in key markets, and having already sold many models with that scheme. We can try and rationalise what real benefit Peugeot gained till the cows come home but at some point they would reach the end of the range X09 (eg 209, 309) ...
Actually, Peugeot has already had a 309 in the late 80s - the rebadged Talbot built at Ryton. Peugeot stopped the numerical progression in 2013 so all models are now X08s.
Did Peugeot ever object to Ferrari's use of 308?
