I have been keeping a close eye on the value of my car, from when we ordered a new LR Trophy in November.
The price has bobbed around a little over the last few months and we have also added about 2,000+ miles to the car.
However the price from WBAC is still the same as the original quote from them, back in November time.
Carzoo have been offering better prices than WBAC generally, but maybe there prices have now levelled out ?.
I would recheck your valuation again in a few weeks time, as prices do fluctuate given how many cars of that type are available for sale.
