2006 Ford Mustang V6 Standard 2dr Convertible (4.0L 6cyl 5M)
Bought the car with 9,000 km and 11 months old. The car has 90,000 km as of May 2010. The car has been bullet proof in terms of reliability. I have just replaced the tires and the original battery. The only issues have been: Engine check light on briefly at 87K, and self-cleared (must have been a loose gas filler cap), and the rear tail light bulbs blow every 15K or so ($4 bulb-big deal). Other than that: just oil and filter changes. Car has been very reliable and solid. Body creaks/groans at 90K are still minimal, but you can now tell the car is nearly 4 years old, lots of life left in it. I will replace shocks & struts this year and this should solve the problem.
Convertible top well designed: car parks outside mostly and does not leak.
Better engineered rear suspension for even better cornering; a wee more power for the V6 (maybe 230 stock??)
