Larry,
P2125 here
Without going into details ( I don't think it serves any purpose to mention the specific problems) I have had issues but nothing but great things to say about how Superformance has responded to my needs.
We need to hear about your specific issues but, some buyers are unaware that these cars (all of the breed) are not a Lexus but, one off's that will require attention, tweaking and upgrading. Most of us recognize this and understand it is part of the "experience".
My dealer (Olthoff) has been GREAT to deal with as has Lance and Barry in Calif. with whatever warantee issues, and fixes I needed.
Can't understand how I have been so well taken care of and your experience is so different.
As others have said it isn't fair to not provide details.
Let us know what's wrong, mayybe we can help.
Steve
PS...Take a look in the Superformance Forum for lots of discussion about the cars and see mine with lots of pics in a posts with P2125 in the title.
