Wow $80K is about what I paid for in total for my 2013 e92 M3 ZCP DCT that had a $76K MSRP plus all my mods which include an ESS 600 supercharger plus an Akra slip with catless mid pipe and a progressive meth system). So for $80K you can get a new M3 built exactly how you want with likely similar acceleration numbers, track capabilities much better daily drivability/looks/appeal and you aren't settling on anything....oh, except I guess the warranty. lol.
