Research the variant, not the model.

30 further makes are listed and not yet researched — coverage is deliberately deep before it is wide. Every step is a page in its own right: stop at the chassis for the engine matrix, or go all the way to one engine.

Look up a failure

79 records, each written once against the engine, gearbox, chassis or component that carries it — and listing every variant affected, with what it costs to put right and whether you can check for it before you buy.

Start where most people start

The E9x 3 Series is the deepest part of the database — four bodies, 65 variants and every issue recorded against the engine, gearbox or chassis that actually carries it.

We document the level
that decides the purchase

  • Written once, inherited everywhere

    An issue is authored against the part that carries it — engine, gearbox, chassis or component — and every variant fitted with that part inherits it. No copy-paste, no drift between pages.

  • Prices with a stated basis

    Every band says what it covers, which market and which window, and flags that the figures are illustrative placeholders rather than a sourced sample.

  • An inspection you can actually run

    The same records, reordered into the sequence you can check them in: cold start, static, drive, paperwork — with the walk-away items marked.
