Update: Built a Chrome extension for BCA auctions 🚗💻 (early access coming)
Hey everyone,
A while back I posted about a tool I was building to help with BCA car auctions, and I got a really good response. Thanks for all the feedback! 🙌
About me: My brother and I are software engineers that made this tool for a friend who works as a car trader in essex
It was previously a locally hosted app on my friend's laptop - I’ve now turned it into a Google Chrome extension that works directly on the BCA site. It shows you:
- A suggested max bid (so you don’t overpay)
- Market demand → how many similar cars are listed and how long they’ve been sitting
- Average resale prices and demand in your area
Here’s a quick preview of what it looks like in action. ( i am still tweeking how it looks, happy for feedback)
I’m planning to share early access with a few users this month to get more feedback before opening it wider.
If you’re interested, check the comments.
Would love to hear your thoughts — anything you’d like to see added?
