TP-
I could not agree more with BlackJack or Mr. Mike. Get what you want, and don't worry about the wait. The wait depends on a lot of factors and will probably vary somewhat. Peter told me 12 months, but it looks like it is going to be a little shorter than that (if every stays on schedule-- cross my fingers). Plus the waiting time will give you an opportunity to "fix" your garage (don't ask how much extra that adds to the cost of the car or how one goes about justifying it to the wife
) and to think about all of your options, drivetrain options, wheels and the ohh so difficult paint color (I'm now on my fourth color choice, and I thinking about going what was originally my first choice
).
Seriously though, the folks at ERA have been great. I can't tell you how many times I have emailed Bob Putnam with stupid questions or called Peter P. to change my order or add options, and they've always been fantastic to deal with (Peter is always especially happy to hear from me because every time I call him it winds up costing me more $$, but what the he*l, do it once, do it right!!). ERA is truly top notch outfit.
In the grand scheme of things, 5 or 6 months difference is not a big deal to get what you truly want.
Good luck,
Mike
