I think the Veyron is the pinnacle of German engineering in a car, really. Dynamically rock-solid, very quiet despite the ridiculous performance and very easy to drive.
One of the correct things Jeremy Clarkson said in his rather uncomfortable splurge about the Veyron is how mind-bogglingly competent it is. Therein lies its problem with car fans.
Whilst it is pretty much the superlative in terms of things that can be measured for a 'production' car, such surpassing brilliance is not why most people by them. If they were, Italian and British car manufacturers would have gone out of business ages ago. It's a car's foibles which give it personality: the Veyron has none, which limits its emotive appeal.
The F40 will always be more involving to drive, a more raw experience because that's how it was designed as a car. It's probably rubbish to drive through a town centre, ridiculously uncomfortable on anything other than pristine tarmac, but drivers forgive this because of its malleability and tactile nature.
But then the car I aspire to own is a new Audi RS6, not a second-hand Ferrari.
