The service outlined below cost £380, bearing in mind the box sections, doors, bonnet and boot had been wax injected previously. If this work is included the cost would be £480.

BMW635CSIThis 1980 BMW 635CSI is in fantastic un-restored condition, being well maintained from new.  The underneath is in remarkable condition and has been protected well by the factory applied under-body protection. However, after 30 years there were areas where this protection had been penetrated and there was plenty of surface corrosion on the suspension parts.

This car had recently had all box sections including the doors bonnet and boot wax injected and so this was not re applied at this time.
