I must admit to also looking at an S3 to replace my 7.5R. Whilst I love my 8CS and I’d love an 8R, the monthlies on an R simply don’t add up. On top of that, the lack of buttons in the Golf along with no backlight on the heating/sound controls mean that my wife isn’t keen on the Golf..
The S3 still has those old fashioned button thingies and the monthlies are significantly cheaper than the 8R it seems…
If you're looking to move quickly, Audi Belfast have 2 incoming S3s left:-
Navarro Blue Sportback - Comfort and Sound pack (B&O sound, full park pilot, rear camera, and I think, rear heated seats), 19" Trapezoid Alloys, Red brake calipers.
Same spec as above, but in Mythos Black Metallic paint.
There's a £3k deposit contribution right now, and for the mess around that buying from NI for GB seemingly gives, they have given me £1000 discount on top. They will not p/x a GB registered car (VAT declaration red tape), so you'd have to sell privately or through the likes of Motorway.co.uk, Cazoo etc.
With that price rise looming very soon, i'd do it now if you're going to do it. On Sun night, there were 5 available S3s nationally, and now there are 2 - those 2 above.
