Je suis à la recherche d'un Bavarian Technic Cable. Avec le shipping et la conversion US/CAD c'est assez dispendieux présentement de l'acheter chez Burger Tuning... (http://burgertuning.com/scanner.html)
I have a version with unlimited access. If you just want to do a quick ECU mod ro your car, we could meet and you can use it
I got a BT tool right when I got my car... I thought it was pretty expensive too but I use it a lot! Get the 3 vin and you should have resale value on it if you ever want to get rid of it or find a BMW buddy near you and share the costs. It's not really something that you "need" to have on hand all the time but I understand your need.
