Has anyone seen or tried the BMW GT1 that you can buy, for instance on eBay? I always thought it was super expensive, but about $3000 isn't too bad considering you get a laptop also.

I see there is a new one and an old one, and I would be worried about software upgrades etc. Last time I went to the dealer they wanted to charge me $100 just to connect the GT1.

Most likely you need training/practice to operate it.
