Pre 02 had plastic intake manifolds known to crack. Updated ford racing model available. Gas tank grommets go bad occasionally. Fuel pumps aren't overly reliable Interior feels kinda cheap Can't use front cup holder unless you get a short throw shifter Most important: if you change plugs, make sure to use a torque wrench... If the plugs aren't perfectly torqued, they can break... I had one shoot out while I was driving down the road, and it's a very common issue Overall, they're pretty unreliable cars... But I bought it as a toy, drove the piss out of it, and fixed it any time I broke it (I destroyed the spider gears in rear diff at the track) My next fun purchase will be a 03/04 cobra. Loved the car, despite any issues. Spent hundreds of hours on Mustang forums for this model, so if you have specific questions feel free to ask and maybe I'll have an answer for you.
