That would be too much for the Arnold Classic to pay.
That car runs for about 240K - 250K.
The winner of the Arnold Classic gets 130K + a Hummer (30K) = 160K tops.
"1"
An E63 with all the fixings (options) would probably top out a little over 100k.
I don't think that they give Hummers away (maybe the judges do) anymore as they don't make the H2, and H3s anymore.
Seriously, since Arnold is into German cars, I think a Porsche or Mercedes E63 or M5/M6/M3 would be a good addition and a good way around the "Arnold Classic can't give more than the Mr.O" rule.
