The car is highly original except for the wheels and tires, which suggests some wear and tear may be present on other original components, but it's described as highly original. The presence of staggered 18 and 20-inch polished alloy wheels indicates a non-original modification, which can be a positive or negative depending on buyer preference, but it doesn't necessarily detract from the overall condition if well-executed. Power steering and brakes, along with an automatic transmission and V-8 engine, are standard features that do not inherently speak to condition. Overall, it sounds like a car that has been well-preserved but has had some modifications and may show minor signs of age consistent with a 'Very Good' rating.
