Sold for $8,800. I like this post by GTzhp:
"Love my 05 ZHP 6 speed with 140k miles. The M54 straight 6 is very reliable if you keep up with scheduled maintenance, and don’t neglect the cooling system, lots of plastic there. The 6 spd trans should be issue free, unlike the cars with the GM automatic tranny. On any E46 you’ll be addressing a minor oil leak or faulty window regulator from time to time, but when you drive the ZHP you’ll understand why owners easily get over any minor issues."
