If after driving the Mustang, you feel you need another $25k worth of refinement and either want to spend the extra money or spend the same money but get an older car with no warranty (that will be much more expensive to maintain as it ages than the Mustang), buy the M3.
Im probably going to go drive the m3 today, if i fall in love which is a very good possibility im going to get the m3 no doubt and just deal with scraping money together for mods.
I have another question, how much a year would you say i can expect to spend on the car if it's not under warranty?
