What is your
BMW M3 worth?
Free, transparent valuation built on 3,293 real auction sales across the E36, E46, and E9X generations. Every adjustment explained. No signup required.
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 auction data from Bring a Trailer.
Transparent by design.
Every number in your valuation has a reason behind it. No black-box machine learning. No undisclosed weighting.
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.
Spec-specific adjustments
We compute a baseline from comparable sales, then apply transparent adjustments for color rarity, mileage delta, package tier, and repaint status.
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.

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).
How accurate is the AutoArchive valuation?
Every valuation is grounded in thousands of real enthusiast-car 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.
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. Signed-in AutoArchive users get refined valuations that incorporate their uploaded service records.
Why is documentation worth more on enthusiast cars?
Enthusiast buyers pay premiums for cars with verified 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). Coverage is expanding to F8X M3/M4, G8X M3/M4, and Porsche air-cooled and water-cooled 911 generations.
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.
