I HATE this phrase but it's the only thing that it really does ring true for being "it's only worth what some ones willing to pay for it".
So yes it is worth £5500 but no it's not,it's only worth about £500.
All depends upon what it means to someone.
I've got one now, k10 jcn valued at £500,but who's actually going to buy it?
I put j19 hll on regtransfers about 6 years ago and they valued it at £950 (????),never had one query.
Purely horses for courses.
I was told my Beemer plate of M3 evj was worth £3000 the other day.
Can't see it myself.
