I highly recommend test driving one with and without it. BUT don't forget about the stereo choices.

I had an e60 with the first gen I drive. I'm scarred and never want to own a car with it again. I haven't tried the new CCC version in a 135 but for me I hated the knob & functionality. Plus in the 135i you have to accept the ugly dash bulge & side cup holder. Both no go for me personally. I prefer the clean look analog interior.

If I was buying a 135i today finding one with the Harmon Kardon stereo system would be a priority or budget for an amp to upgrade the stereo. I'm not an audiophile by any means but the Base & Top Hi-Fi versions of the stereo are lacking even for a car built 2011-2013.

Is I drive a necessity? Up to you & what you prefer. I'd put more weight into other options/upgrades or no-upgrades/tune done & the maintenance history.
