KBB vs Edmunds
 

I'm leisurely looking at the used EV market again, which has me wondering why Edmunds always shows a much lower private party value for any given vehicle (that I've looked up)? KBB says a 2017 Prius Prime Plus with 39k miles is $20k private party, and Edmunds says it's worth $16k.

While I'm at it, anyone else notice the KBB site has been circling the drain for a while now? It spikes my new gen 10 Intel i5 processor while presenting the least professional web page I've seen, and my cooling fan has to kick on just to display that hot garbage. It's almost not usable.

I use car guru's price trends to track which direction the market is headed, but I don't really have any other sources for private party valuations than Edmunds and KBB.

Of course, everyone relies on KBB, so I guess it's probably more accurate than Edmunds.

I don't have any problems with kbb. It takes its time for the webpage to load, but nothing ridiculous.

When was the last time you recoated your heat sink with thermal paste? I'm not an expert on this, just something I noticed on mine after several years of almost daily use.

My biggest problem on my pc is probably the graphics card (gtx 660) and/or RAM(2x4 ddr3). So I don't usually get the cooling fan for the processor to kick on.

It's a brand new i5, but admittedly aggressive fan cooling is the top/only complaint about this model. Still, I've got 80 webpages open at any given time (I'm trying to quit) and it's just the KBB one that taxes the CPU. No discrete GPU, just the Intel integrated one.

I can't run KBB.com in Chrome because I don't want to turn off my ad blocker, so I open it in IE, which is trash. I get left/right scroll bars to see the page and it looks like a middle school attempt developing a web page.

Anyhow, site problems aside, I wonder which value is more accurate? I see Prii regularly selling for quite a lot above the private party value listed even in KBB, and way higher than the Edmunds estimate. I saw a reconstructed title Prius go for KBB value and asking price, and normally I value reconstructed at 70% of clean title value. Granted, I was able to get a C-max for about that 70% target last year.

I am sympathetic to your plight.

I was going to suggest the alternative I use, but I'm not sure which is the official entry point:

I bought my desktop with an i7 three years ago, maybe four. It came with 16 gigabytes of RAM and the only time that I have opened the case was to install an SSD. I do not care to count my tabs, but I am confident that I have well over 80 open. I think that I just keep Chrome around for KBB. It claims that a fair price for a 2000 HX with normal miles from a dealership is $2,451 and $1,850 Private Party. It also claims that typical mileage on a car that is supposed to get 50 MPG is 153,344.

Something is clearly wrong, but the site looks and runs just fine for me.
