I bought an 06 mustang pony package with 104,000 miles today. I plan on changing the oil to 5w30 Valvoline full synthetic and a motorcraft oil filter. Also changing the coolant tomorrow and inspecting the trans and re diff fluid. She runs good and is a lot of fun. She has aftermarket wheels but thats the only thing that's been changed. I do plan on buying new tires soon as these are going on 6 years old. I paid $4200 for her and drove her 2 hours home. Very happy with her. Fun little car!!
