I would love to get into the new TTS but your looking at a starting price of £40k so I don't see that happening. So I'm probably looking at an R, S3 or M235i as my next purchase in 2 years.
I've heard nothing but rumour about the TTS price. The VAG group generally hold to an exchange rate of 1.20-1.25 Euros to the pound to compare Germany prices to UK prices. You can configure the 2.0TFSI (230ps) and the 2.0TDI (184ps) model on the Audi.de website now. There are no indications as to TTS price right now. The 2.0TFSI (230ps) TT starts at 35k Euros, which should be around £28-29.1k, only £700 - 1800 more than the GTI PP with the same output. I would be very surprised to see the TTS at more than £35k unless it is packed to the gills with equipment that is optional on the base models. With the comparison of GTI PP to GTI PP, the German model appears significantly cheaper, but the equipment level is sparse compared to the UK. By the time you get the German spec up to UK levels of equipment, you are talking over 33k Euros, or an equivalent exchange rate of 1.20 Euros to the pound.
If it were £32k, it would make the TTS over an S3 a probability for me, if it were £35k but packed with around £3k's worth of desirable equipment that doesn't come with the S3 and better residuals than the S3, it'd just about be still in contention. I really can't see the TTS being £9k more than the S3 with an extra 10ps, i'll believe it when I see it for 48k Euros on the German site (or 44k Euros with a very sparse equipment list, lower than UK equipment expectations).
