Hopefully it'll be for sale on the 1st Jan and I'll get it in the data! I missed out last month - a 75 mile, one owner 2005 can up for sale with Graypaul mid month but was sold before I collected the next lot data. The price? £84.5k!!!

[TISPKJ]

Hi mate, yes I saw that in your blog...
Still not worked out exactly how the model works but seems to be in my favour so will keep quite :-)

I am not surprised the 360 is the last of the the breed of relativly pure ferrari what would they ask for this in red and cream...?

I saw that car on Monday - it had been sold along with a 355GTS with less than 2k miles on the clock for around the same price as the 360. Appears they've gone from one collector to another.

So what's the silver car worth then? I reckon low miles manual in an unpopular colour 45 if its serviced fully.

[TISPKJ]

No, bit better than that, as above 55k tops is about right.

Thanks for the update and for confirming that it was indeed sold.

Chancers. They know they are going to be stocking them over winter and if anyone was vaguely interested they would want a deal / massive over allowance.
Both cars £10k over priced IMHO but that's good value compared to CS.

I might think of a figure and add a zero when I come to sell my car

2nd car looks like could be part of the same collection as the 360

The 389 mile one up for £110k has been in my data for the last two months now. I'm going to try and build in a tracker to keep an eye on how long cars have been advertised for. I think that the correctly, ie: cheaper, priced cars are selling and leaving the optimistically priced cars on the market, hence the firming of prices last month.

If the idea is to build a real world valuation model would it not be better to take out the anomalies at each end ?
Or does the model not use averages (sorry charts not my area) ?

I think this is correct - both owned by the owner of Frosts garage group in Sussex given the number plates??

[Jonty355]

355's should be about 100k then if 360's are going for £70k.

[TISPKJ]

Will ne interesting to see if they go the same way as the 993 / 996 mkt

I'm not trying to build a real world valuation model, I do enough of that at work thanks! It's just a bit of fun to keep track of prices and see what the market is doing. The biggest issue is that the data is comprised of asking prices which are different to sale prices, although both should be well correlated.

The index is simply an average although I will consider changing the calculation to remove the outliers.

The mileage vs asking price formula is just a best fit line over the data and just provides a guide as to the link between these two factors.

Don't forget that the data cannot take into account condition which is the most important thing people should consider when buying/selling.

I could create a "prime" sub-index, based on asking prices from specific dealers, which could attempt to isolate cars you'd actually want to own. I'd need a list of dealers to include - any suggestions?
