I have a trophy, and had a 182 cup at the same time. Also had a FF in the past. The trophy does feel noticeably different. However, you could achieve the same/or better handling by upgrading your FF. For me, it was never fully about that though. It was more the mysticism of owning a trophy...
Going off those numbers, mine looks just below average mileage, is probably bang on average condition. So now just need to figure out what an average price is.....
If you can afford to, and have the space, then I'd keep it. If you're using it less then you'll probably appreciate it more, especially if youre getting jobs done on it gradually. Unless you think someone would appreciate it more than you.
Think someone asked the same yesterday. Appears to be very little documented for it. I'd just message the dealer and ask for the reg and service history. Seems to have the standard peeling heater panel issue.
