I'm all for the GAP too, and own one myself. That said, I support more affordable options, which the Autel tool is. It will do most of what you need, including suspension calibration. I'd think about exactly what you want, and contact them to confirm their scanner can do it for your VIN.

 

Can the Autel do all the software updates? GAP is only $500.

 

When I'm bored, I sometimes spend 3 minutes and approximately $25 (cost of new key + keycut) to program a brand new Key, using the BRILLIANT Gap tool. In other words, I save approximately $600 and hours of wasted Stealership time. And I tell my wife that I have just saved us almost $600, and I proceed to cleverly use that fact to negotiate buying additional new tools and gadgets. Win-Win!! P.s. At this point I think I have about 7 spare keys, and therefore lots of tools and gadgets...

 

the best all around tool is the GAP IID Tool.. You could get away with advanced code readers that read multiple systems.
