not your last! why not pick up an e30 now. should make a nice set
i think you shouldn't be too hung up on this though. life is about change. give the M4 a test drive. you might like it.
i drove 991 C2S a few times now and own a 997. before i was no way i would buy a 911 with an electric steering and sound tube. well 991 kicks butt! love it! not sure i would want to part with my 997 as it is now even more of a classic. but i have my eye on 991 turbo. maybe slightly used
