Right first off the gent has his heart set on an A6 2.0tdi s-line Avant. Which in itself isn't exactly poverty spec and is all that will sell under our current regime. And I can't see how its paddy spec - there's 10odd grand of extras on it, which is what most people spend on a car. And its an avant which is an 'option' as well.
People refer to paddy spec as if the rest of Europe's a6's and 5er's are dripping with the entire contents of the options catalog. UK cars may be specced with what? sat nav over an Irish car. Yay! I never found a need for one in Ireland to be honest.
The simple fact of the matter is that most people select an option pack and maybe leather and metallic and live without the magnetic dampers and lady boy massage seats.
I have all these options on my car because some company bought it initially for a director who left after 11 months and they've taken a heavy hit on it.
If I was buying new I'd pump for the 3.0tFsi quattro because I like power and you need RWD or AWD in my opinion but I don't live in Ireland any more; I don't face the same market conditions and ridiculous tax systems!
I can buy a new Audi with a huge discount from both the euro bonus (chf strength) and fleet discounts available and lease a fully optioned A6 for less than a 1000 francs p/m
That option in Ireland simply isn't available!
Go for it OP and just get the price to a level you are happy with or having a service package or extended warranty thrown in would be a nice bonus.
As for a year old demo or what have you - well you won't get an avant and the only 3.0tdi avant for sale is €74,995! Bargain.
