I’d imagine a little Charade GTti would be mega rare now.
To be blunt, unless you have a deserted runway at your disposal or do autobahn trips then no, you’d not use much of the R’s potential performance.
To make the most of an R you’d need to spec the performance pack too, then by the time you’d added paint, leather, sunroof and camera you’re pushing well towards £50k.
I’m sure the R forum is awash with those who buy fully loaded R’s just because they can. What you need and what you buy are often different things.
