I own a 03 Mustang that I bought brand new back then, so these are some things I noticed.... I think the interior quality sucks. There are lots of weird rattling noises that come from the dashboard that randomly appear and disappear. The cd player really sucked... It skipped a whole bunch and eventually started making weird noises and spitting the cds out scratched. At first, the mechanical features had no problems but after a while, the engine noise started to sound kind of strange. It started making a ticking sound kind of like when you stick a piece of paper into a fan and hold it there. The suspension of the car also started having problems later and they squeak when you make turns. . The reason I initially bought a Mustang was because it was pretty cheap for a fairly fast sportscar. However, I regret buying this car. Though it has pretty good performance for its cost, I think overall it is unreliable and has too many problems. I would recommend spending a bit more money and buying something more reliable like a BMW or something.
