What's the worst surprise you've found after buying a car at auction?

Last year I bought a 2019 Audi A4 from a US salvage auction. I'd budgeted $4,000 for repairs. It ended up at $6,500, and I spent days just figuring out which parts I actually needed and what they cost.

That's why I'm building Partsify: paste a Copart or IAAI lot link and get the visibly damaged parts, their OEM numbers, current supplier prices and estimated labor hours, before you bid instead of after.

We launch here on Product Hunt tomorrow (Wednesday). Before that, I'd love to hear from anyone who has bought at Copart, IAAI or any salvage auction:

1. What did the photos NOT show you?

2. How far off was your repair estimate from the final bill?

3. How do you estimate repair cost today: a mechanic friend, a body shop quote, gut feeling?

Every answer helps shape what the report checks. Here's a full sample report for Porsche if you're curious what it looks like: partsify.io/sample-report
