Yeah I know about MachV. Heard good things from them too. I've purchased a few things from them online. And I've stopped in to Agile and talked with those guys too. IAG does usually have a long lead time. Usually 4-6 weeks out. But I never need anything done fast or I plan in advance so I just wait whenever I need service.
I haven't had a need to really get much done other than routine maintenance. IAG has done all of my alignments, my short shifter install, and my 30k and 60k services. After I get myself a down pipe ad heat wrap everything, they will likely do my tuning too.
I do my own suspension work, as well as anything else I want. Oil changes get done at the dealership for free (for life).
