i am looking into buying used 2013 m5 with 24k miles on it. sakir orange color.
carfax is clean 1 owner but first registration was at 4k miles and the car was used in north carolina at bmw driving school so i think those 4k miles are all track miles and the car was driven hard and abused.
the car has all bells and whistles 20 inch wheels, exec, cold weather, drivers assisstance, night vision, heads up display, bang olufsen audio.
warranty expires in 11/2016.
price is 58k.

1)should i go for it or let it go as it was a track car first 4k miles atleast?
2)i was thinking g10 m5 will be out next year and f10 will suddenly look old?
3)g10 m5 will have awd so better 1/4 mile performance.
