Kin Mak said:I guess I was in the same situation as you so I should post my 2 cents.
I had an option between a E46 M3 SMG or a E39 M5. Both with TV, upgraded sound systems... I wanted the SMG for the option of driving in auto when I was tired or just wanted a lazy drive. Differences between the 2 cars I noticed that mattered to me are.
Auto driving option (I quite liked the SMG)
More suited to my age (26)
Power, yes you do notice it
Comfort & Ride
The noise of the 5L V8
I have to say the thing that swung me the most was the fact that the M5 was 99(reg in Nov) with 45k and the M3 was 02 with 33k and the price difference was that the M5 was €25k cheaper.
Both equally good cars but each better suited to different drivers. In the end you can't go wrong with either.
