£25k - a combination of things.
1. Valued it on Autotrader and a couple of other sites.
2. Fundamentally, the car hasn't sold.
So, if it hasn't sold at £30k, people will offer £25k. That's assuming the owner has received any offers at all?
You have to remember what you are up against when selling an RC-F carbon.
1. BMW M4s are now hovering just about £20k. Right or not, the industry sees the M4 as a far superior car.
2. Those people knowing about F cars are few and far between. So the market is very small
3. Those that are in the know are going to be Lexus fans. Many of these will consider the carbon edition as too 'Halfords'. People on here have commented before that the carbon bits just don't look right.
Finally, I will point out that I am not bashing the RC-F carbon. I was after all (probably) the first member on here to own one and have a full understanding of what the F brand is all about.
However, I don't have a romantic view on the value of such vehicles.
