I'd go for the bimmer but that's cuz I'm a total bimmer enthusiast. as for modding. there's more options than just m-technic.
if you can't drive stick then ask about smg upgrade. it might be available for new models. I know it's an available upgrade for the E46 M3.
I dunno about 5 series but for 3 series you can go with ac shcnizer(sp?), Racing Dynamics, Reiger just to name a few. for lighting you can go to mts, hella, etc... the 5 series already has angel eyes and maybe HID..or at least H3 bulbs so lighting prolly won't be a concern.
there's lots of options bodywise for bmw.
as for performance, like you said, ECU and a CAI(Cold AIr Intake) are probably your best bets. if you wanna dish out more cash you can go for like performance exhuast, cam shaft, headers, etc...
but I were going for a bimmer I'd go for a 3 series. they're smaller and they look better in my opinion.
