Money well spent! Your best 'mod'?

[e34.535i.sport]

I took the car out today to see a guy about some rubber (Interpret that how you will ) and as I was driving around I just thought to myself how the lowering springs I invested in recently were money really well spent! The car feels like it has a new lease on life and you couldn't pay me to change it back. Easily the best £100 I've ever spent on my old banger ... (Although I think the T-Stars may come in a close second once I get then on!). I would seriously recommend this spring chang to anyone as you get such a lot for so little expense.

I thought I would share the joy with you and ask: what's been your best mod/upgrade/addition to your e34 be it performance, asthetics or even functionality?!

So far, my CD/mp3 head unit, with now a box to add iPod connection and control. Still with stock amp and speakers, the sound is actually good.

So far HID's and 6-disc CD changer. Next I want to get a 5-speed swap with an LSD.

I think my best mod has been the EAT chip, but its a real close run with the 5 speed manual in place of the auto.
