Are crash repairs costly

The cost obviously depends on the amount of damage, however, relative to other categories of open-wheeler racing, and any other form of circuit racing, crash damage is far easier and less costly to fix. Most suspension components are standard VW parts, so are simply acquired from your local VW performance supplier or wrecker. Wheels and brakes are standard automotive components, and the chassis are a mild steel space-frame chassis, and so can be repaired quite easily if required, although hardly any crashes will inflict chassis damage.
