I purchased a 2008 v8 coupe this year with 32,000 miles in great condition. Having researched low and higher mileage R8/v8s it seemed that they lose 10% of their value for the first year and then about 5% each year after that (% reduction based on previous years value). For mileage above 4,000 per year it seemed the market deduct was in the range of $0.25 per mile. So for my 4-year old R8 with 16,000 "extra" miles this would equate to a $4,000 additional reduction in value since new. Now that this car will only be driven by me about 4,000 miles per year it should revert to the approximately 5% per year value loss in the future in my opinion.
