Looking at a 2014 Recaro from a Nissan dealer, so standard spec and with a years warranty around the £52k mark. Excluding running costs what depreciation should be expected over a couple of years, would keep it standard and and fully serviced.
I believe they seem to bottom out around £35-40k for the older ones with some miles on them but it depends on you keeping up with the service history and getting it done properly. Whether it is modified or not (so long as it was done by a shop) doesn't seem to matter.
