C8Tracker : For All Your C8 Corvette Data Nerd Needs

/ Home

Hi.

This site was designed to gather information about C8 Corvettes and make it available for Corvette enthusiasts. The information on this website came from downloading and analyzing the window stickers for new Corvettes. The site checks for new window stickers every day, but just as cars are not built every day, window stickers are also not created every day. The window stickers for each car typically becomes available within a few days of the car being produced in the factory. Keep checking back for the latest data to be added to the site.

This site is actively developed every day, so it is constantly getting more data and features.

The window sticker data is publicly available information that is collected and presented on our website. This website is not affiliated with General Motors, Chevrolet, or any of their dealers. We do not have any dealers or GM/Chevrolet employees feeding us information.


/ C8Tracker Changed Over to MY2025

Posted on 9/23/24, 10:22 PM

The MY2024 window stickers have slowed down to a trickle.  As of tonight, the MY2025 stickers haven't started getting released yet.  But they should be really soon, so I went ahead and changed the site over for MY2025.  All the previous year data is still there, you will just have to select 2024 on the different pages to view it as 2025 is now the default option.  Once 2025 stickers start coming out, the data will immediately start showing up on C8Tracker. 



/ MY2025 Production Scheduled to Start Monday 9/9

Posted on 9/8/24, 10:18 PM (Edited on 9/8/24, 10:21 PM)

As you probably know, the production of model year 2025 Corvettes is supposed to start this week.  When 2024 cars started getting built last year, there was a delay of about a week or two where the cars were getting built, but the window stickers were not getting released yet.  I assume there was just a mandatory quality control hold for all cars for the new model year.  I would expect to see the same thing happen with model year 2025.

So the C8Tracker scheduled daily updates will still search for model year 2024 cars.  Later in the day, I will check to see if 2025's window stickers have started getting released yet.  When the 2025's start getting released, I will change the site to start primarily looking for 2025's.

Since 2024 stickers will still trickle out over the next few weeks, the site will continue to search for them, just not as often.  Instead of daily it might just be a few checks per week.

I have all of the site code updated to handle the 2025 data.  When these stickers start coming out I will push out the updated code.  Then C8Tracker will be fully in "2025 mode."  I will make an announcement on the site and the Facebook page when that happens.

ZR-1 data will not be added to the site at this time, as those cars are not getting built any time soon.  I will add them when ZR-1 production starts.  But that isn't happening any time soon (the actual production start date hasn't been announced).



/ Bowling Green Closed This Week, Might Still See New Stickers Released

Posted on 7/2/24, 9:39 PM

Bowling Green is closed this week for Independence Day. Usually, these holiday closures mean no new cars will be going down the assembly line, but we still usually see some new window stickers coming out. I have no way of knowing the how or why, but I assume this is cars getting cleared from QC or whatever delay the experienced, then getting invoiced. Today we saw 55 or so new stickers, I assume we will see more during the week. But who knows for sure, its been pretty unpredictable for the last month or so.



/ New Window Stickers Today

Finally, some new window stickers today. There were 700 or so added to the database today. Unfortunately, the stickers from last week seem to be clustered in a few different dates, so this will throw off the estimates in the Daily Dashboard. Whenever the release of the window stickers gets back to the normal cadence, that will be a self correcting problem.



/ No New Window Stickers

Posted on 6/19/24, 2:30 PM

The issue with the window stickers is still going on.  For whatever reason, there have been very few new window stickers for the last couple of weeks.  There have been none since June 12.  It seems plausible that this is related to a parts supply issue, either related to the seat belt recall or something else.  Other data sources make it seem like cars are still going down the assembly line and being built, but the lack of window stickers typically is a sign that none are being invoiced and shipped to dealers/customers.  This appears to be an issue specific to Corvettes and not all GM vehicles.

I'll post another update when the window stickers have started working again.  For now, the site will keep on checking and hopefully things return to normal soon.



/ Improvements in the Works for C8Tracker

Posted on 5/29/24, 5:54 PM (Edited on 5/29/24, 6:42 PM)

Hey everyone, its been a while since I really posted an update to the site.  I've been tied up with other projects so I just haven't had the time to write new code for C8Tracker.  My focus has mainly just been on keeping it running.

Over the last week or two I have been working on rewriting the code that downloads and processes all of the window stickers.  I am just about done with the work.  Everything looks like it is working as it should.  The big difference is a drastic performance improvement.  

The old scripts were a long and slow process.  The script that pulls the data to populate the Daily Dashboard would take about 15-20 minutes to do its thing.  The script that handles the big updates every day (downloading all of the new window stickers and adding them to the database) generally took about 2-3 hours to do its thing.  It was a long painful process.

The new scripts are running about 90% faster.  The new Daily Dashboard script takes about 2 minutes to complete.  The big update script took about 8 minutes when I tested it earlier.

My goal here was a bit selfish... I wanted C8Tracker to the the first place on the internet to have the latest data.  The hope was that this would simply increase the usage of the site haha.  But either way, it was a fun exercise and I learned quite a bit.

A secondary side effect is the new code is better at processing the Canadian window stickers.  Right now it is able to pull all of the options data.  The only part I can't seem to grab is the MSRP on the Canadian window stickers.  I'll work on that some more.  But once this code is done and live I plan to write a script to populate the database with all of the missing Canadian option data.

Testing of the new code is going well.  Hopefully starting next week it will be live on the site.  I'll make a post when that happens.  I just wanted to let everyone know what is on the way.



/ Daily Dashboard Improvements

Posted on 2/22/24, 2:08 AM (Edited on 4/7/24, 10:10 PM)

I think I have the new Daily Dashboard pretty well dialed in at this point. For most days it appears to be coming up with accurate numbers. The only exceptions are when the plant is closed for a holiday, or maybe when the plant runs on a Saturday. It's difficult to have it account for those oddball days since I really don't know when that is going to happen ahead of time (and my insistence on automating this entirely). Holidays seem to be tricky because while they may not build new cars on a particular holiday, sometimes window stickers will be released on those days. So that creates some challenges in these calculations. But holidays like that aren't super common so its not a big deal. I think about 95% of days this dashboard is showing accurate data.

I have a new script that will run tomorrow a little after 11am. It is simply designed to find the highest VIN window sticker for each model as early as possible in the day. The goal here is to get this Daily Production dashboard populated as early as possible. Once that script is done the normal daily update will kick off.

Right now, if there is no production for any given day, that day just isn't displayed in the table. I do want to go back and make it add those days and just report 0's for the data, but its not a critical feature or anything so I'm not sure when I'll get to it.

I think for now this dashboard is pretty solid.
