AI Listing Summary
This 2006 Mazda MX-5 Miata has been significantly modified with a GM 5.3L V8 engine swap, a rebuilt automatic transmission, and updated suspension, featuring a Holley digital dash and 17" wheels. Recently refreshed in 2024 with a new soft top and interior updates, it presents as a unique build with records supporting the major mechanical work completed in 2022. However, potential buyers should note a mileage inconsistency reported on the Carfax and an unknown total mileage, though the odometer shows only 930 miles since the engine swap.
Condition
7
The car has undergone significant modifications, including a V8 engine swap and transmission rebuild, with records indicating these were done in 2022. The cabin was refreshed in 2024, and a new soft top was installed in the same year. While the Carfax report is damage-free, there is a noted mileage inconsistency and the total mileage is unknown. The odometer shows 930 miles since the swap, but an April 2024 entry on Carfax shows 100,100 miles. The vehicle is described as having aftermarket suspension components and being fitted with a mixed set of tires. Given these factors, it falls into the 'Very Good' category as it's a heavily modified vehicle with recent refreshes but unknown total mileage and some noted inconsistencies.
