LOL...It was only a matter of time before 135i owners, having been king of the hill, are now knocked off by the superior 1M.
I bought a 135i in Jan, knowing I could get the 1M if I waited. However the $ difference didn't warrant the trade off in performance. If you spend $4k on wheels/tires, tune and suspension on a 135i you'll have a brilliant car...a touch behind a 1M though.
The 1M looks fantastic too with the quad pipes and flared arches :-)... i'd love one, but a 135i with performance mods does very nicely!
