I'd bookmarked the search page on AutoTrader, and regularly went back to it to see if they were any cheaper. Low and behold, the cars were depreciating, but it was a drag having to go back to the site each time. I was too lazy to put the prices and dates in a spreadsheet.
Writing this little app seemed like way less work (it wasn't, but whatever). I thought it might be useful to other people, so I bought a domain and here we are.
Would love feedback! Would this work in the US? What are the large car sites in the US?
With time most models will see an exponential decay, according to my analysis. But some will, of course, decay faster than others.
I once wrote something sorta like this for motorcycles, which are easier to compare due to fewer model options. My goal was to identify what brands or models held their value well (Hondas and Harleys mostly) and to automatically alert when one fell below the curve by X%. I never got much out of it, but it was a fun project.

I want to track how quickly the price of that model was dropping. Hopefully over time a nice curve will be produced.
If we spot that the lowest price has changed from the previous day, we'll email you an alert right away.
Do you do anything about sellers listing cars at £0, £1 or some other below market value? What about excluding cat d cars, etc?
Haven't written a price cleaner etc or started looking at crash recoveries - quite a bit more tricky! Also PH allow e.h. 996 C4S to be advertised as 996 Turbos as they have "Turbo Bodykit" or somesuch which is really annoying. I blame Porsche drivers ;)
