Stop losing money on salvage lots: a pre-bid checklist

The Parts · Jun 27, 2026

Most small dismantlers lose money in the first ten minutes of a deal — at the auction, not at the teardown. The bid is a bet, and too many bets are placed on gut feel.

Here’s the short version of how to bid with numbers instead.

1. Start from the parts, not the car

A donor isn’t worth “what the car is worth.” It’s worth the sum of the parts you can realistically pull, list, and sell — minus everything it costs to get there.

2. Subtract the real costs

Acquisition price is the obvious one. The ones that quietly kill margin:

  • Auction + gate fees
  • Transport
  • Storage / days-to-sell
  • The parts that never sell

3. Know your number before the lot opens

If you can’t say your maximum bid out loud before bidding starts, you’re gambling. A pre-bid estimate turns “looks like a good car” into “net profit at $X, walk away above $Y.”

This is exactly what The Parts’ Pre-bid ROI does — VIN in, projected parts list, estimated revenue, fees and net profit out.
