wow cant believe I just saw this thread!!! Deff. in for updates, and if this kit is launched at a decent price ($5K range for a good stage 1+)...then the 335 will be THE Bmw to own, for all the reasons already stated above.
Its like when they came out with their E46 M3 turbo kit, how many people have bought USED E46 M3s JUST BECAUSE of the HPF KIT...
