Yes, its the same price as getting it done at the factory and thats because the retrim was done through the Audi garage, that meant I got a better guarantee,they organized it all, a courtesy A2 for a week with a full tank of free fuel, a choice of materials, and best of all the choice of over 100 different colours.
The leather was installed about 3 months after purchasing it new, and yes I did "just stroll in" and say I wanted it. When I was buying the car they told me that if I wanted the leather fitted afterwards, it was no problem to get it done.
It's the only good thing Lomond Audi have done for me.
P.S. The stitching on my seats is blue not black, it looks a lot better than plain old black.
