Since you've been waiting a year and had trouble trying to find an R your happy with have you considered ordering new?
Drive the deal are under £32,500 for the same spec as that car, means an extra year and half warranty, 3.9% finance from VW if you need it - if not can take the deposit contribution and then pay off the finance straight away (rate varies every quarter so has been lower) can pick and choose what spec you'd like and avoid any hassle. I got a local dealer to match the price from drive the deal and ordered new, as nearly new ones weren't that much cheaper, and with 15k miles that car will potentially need some new tyres soon if the dealer isn't already replacing them, and a 2nd service in 6 months, so begins to close the price gap more.
About 9 weeks later you could be driving out in your perfect spec R 👍
