Why we exist

KBB doesn’t know your spec. We do.

Generic valuation tools treat configuration as noise. We price every attribute: year, body style, transmission, color rarity, package tier, mileage, modifications, repaint status; using real, public auction results.

How it works

Transparent by design.

Every number in your valuation has a reason behind it. No black-box machine learning. No undisclosed weighting.

01

Real comps

We gather every recent documented sale of your model from the public auction market. The engine filters to your body style and transmission, then time-adjusts each comp to today's market.

02

Spec-specific adjustments

We compute a baseline from comparable sales, then apply transparent adjustments for color rarity, mileage delta, package tier, and repaint status.

03

Confidence-weighted range

Cars with abundant data get high-confidence estimates within a tight range. Rarer configurations get wider ranges with explicit warnings. We tell you when we're uncertain.

A valuation is an estimate derived from what comparable cars have sold for. It is not an appraisal, an offer, or a guarantee of what yours will fetch. It can’t see the condition of your car, and the market moves. Treat it as a well-reasoned starting point.

FAQ

Common questions.

How is the AutoArchive valuation calculated?

AutoArchive valuations are built from real, documented sales of cars matching your exact specification. The engine establishes a baseline from comparable sales, then applies clear adjustments for mileage, color rarity, package tier, and condition factors. The tool currently covers the BMW E36 M3, E46 M3, and E9X M3 (E90/E92/E93), with 2,939 sales behind it.

How accurate is the AutoArchive valuation?

Every valuation is grounded in 2,939 real sales and returns a point estimate alongside a confidence-weighted range. Cars with plenty of recent comparable sales return tighter, higher-confidence estimates; rarer configurations return wider ranges, and the tool tells you when it is less certain. Each estimate shows how many comparable sales informed it. It is an estimate from past sales, not an appraisal, and no tool can price the specific condition of a specific car.

Is the valuation tool free to use?

Yes. The public valuation tool is completely free and requires no account. You can value as many vehicles as you want.

Why is documentation worth more on enthusiast cars?

Enthusiast buyers pay premiums for cars with documented service history because documentation reduces risk. Auction comment data from the enthusiast market shows recurring patterns where bidders state they would have bid higher with documentation. Our analysis of E46 M3 sales found documented higher-mileage cars sell for roughly $4,000 more than comparable undocumented cars, with smaller premiums on lower-mileage examples where condition speaks more loudly than paperwork.

Which makes and models does AutoArchive Valuation support?

The tool supports the BMW E36 M3 (1992-1999), BMW E46 M3 (2001-2006), and BMW E9X M3 (2008-2013, including E90 sedan, E92 coupe, and E93 convertible). More chassis are in progress, each generation launches only once there are enough real sales behind it to be worth trusting.

How is this different from KBB or Hagerty?

KBB treats configuration as noise, returning similar values regardless of package, color, or transmission. Hagerty provides broad ranges without distinguishing spec attributes that meaningfully affect value. AutoArchive prices every spec attribute using real auction data and shows you exactly how each factor contributes to the final estimate.
