The 2006 Mustang is available as both a coupe and a convertible, powered by either a V6 or a V8 engine. The V6 Deluxe comes well equipped for less than $20,000. The Mustang GT boasts a multi-valve, overhead-cam V8 that produces 300 horsepower. Both are available with a manual or automatic transmission. More importantly, both deliver the bold styling, rear-drive performance and affordability that have been Mustang hallmarks for decades.
