Specific notes from the seller include: a small paint blemish on the bonnet - it looks like the clear coat has started to fade in a spot; general wear and tear under the front bumper; minor white paint on the left-side mirror; a minor chip on the right-side door; small imperfections on the rear bumper; the passenger seat has a small leather imperfection; the driver’s seat leather has small imperfection; the roof liner is starting to come unglued from the roof in a a small area above the driver’s head. The seller notes that on startup, the car gives a warning about ‘service suspension’ due to the coilover upgrade. The factory MRC setup wasn’t deleted so it can be restored to factory MRC shocks if desired. The ECU has been reprogrammed so the warning reportedly has no impact on the car’s handling or performance. The car’s last service was completed in August 2025 at an indicated 125,066 km, when Von Vibra Holden replaced the engine oil, oil filter and air filter. The seller states that some suspension bushings have been replaced.
