    How much did you pay for your ZHP - Data Collection/Consolidation

    EDIT (3/1/17): I'm obviously not on this site any more as I ended up buying an e90. I did realize today that my data collection chart was still being used by wasn't updating correctly. I fixed it and it should be working correctly again. If it screws up again you can find me on e90post.com


    What I've done is created a way to catalog some key data from your ZHP purchases with the idea that it would help buyers and sellers know what ZHPs are going for.

    So, rather than enter your data as a comment, simply fill out this:
    USE 4.9.16 LINKS AT END OF THIS POST
    form.

    As an example of things you can do with the data, I will plot purchase price vs. miles at purchase for purchases made 2013 and later. The chart can be found here.

    If you want to see all the data collected, go here.

    Let me know if you think other data should be collect with the understanding, the more you ask for the less likely people are to enter it.

    Updated links as of 4.9.16

    This should be very helpful, especially if it can be populated by older data as well.

    EDIT: is there any way to add the purchase date to each data point on the graph? I think that would help give some historical perspective but I have no idea how powerful Google's graphing software is.

    Awesome idea. This though would be a big factor in what the car is worth today. I mean... buying a ZHP with the same mileage today for the same price as what they went for 5 years ago is crazy talk, which I'm seeing a lot of recently.

    Thanks for making this form. It definitely makes it easier to see than having to read through a huge thread that we have on here.

    It's not the car you drive, it's how you drive it.

    Not that I know how. The features seem to be pretty limited. One of course could always copy the spreadsheet and remove the data they didn't care about.
    I could probably figure out a way to only include the last 18 months or so in the plot. I'll have to thing of a way to automate that, but for now, it's time to go back to work.

    Hmm. Thinking about it, if I was to input my data now, I'd have the only car with 75k on it purchased for $18k amongst the existing entries, which on the plot would make it seem like I way overpaid for my car, when in reality I bought it for average asking price. It was 5 years ago though, so that's an important data point.

    Too bad the data plot can't reflect that. Otherwise, I love this idea.
    If anything, the month/year purchased could just be a text only field on the main spreadsheet, so that if someone wants to see why a particular point on the plot is so far off, they could just look it up.

    I didn't even know Google had this feature. Pretty neat!


    EDIT: I just went to fill the form out and noticed the "what year did you buy it in" section... was that always there (did I miss it) or did you just add it?

    Ok, I modified the link in the original post to only plot purchases from 2013 to present. Hopefully this will make the data more relevant. If we get more data points, I can restrict the plot to only 2014-2015 purchases.

    I think it's fully automated but won't know for sure until someone else adds a recent purchase.

    the car's condition will invariably affect it's price - i got a great deal on mine, but i've also put a lot into it to bring it up to where it should be. can we add a column for "what did it cost to make it 100%" or something like that?
