I had an R32 in the Middle East when I was there. Standard things to ensure is that the Haldex servicing on the gearbox is up to date, because if it isn't you're looking at some interesting bills. Most of the 3.2l things of that era are quite collectible nowadays, so it might well be a sleeping earner.
There was a fairly limited version of the TT released with an interior the same colour as a baseball mitt - complete with glove style stitching on the seats. Also, a denim coloured metallic blue paint was available as well. Pretty sure this combo was only available on the earlier 1800cc models.
As with all VAG cars of that period, they weren't the best as far as component lifespan because of funds being diverted into the loss-making Veyron project.
Like everything German, as long as it's been looked after properly, it'll go on forever.
