The Alpina was a limited run(only 555 made) special edition Z8 which had 20'' bling wheels, automatic tranny and detuned(to 375hp) V8 engine for around $130,000. They are decent cars that are unique but as mentioned already they are no powerhouse or supercar. I used to work on them when I was with BMW of NA, only their 3 training centers in the USA are allowed to fix the Z8's when structurally damaged because it's an all aluminum car and a pain in the azz to repair. The coolest thing about the Alpinas to me is the back cover of the laser cut key is a metal plate with "Alpina" and the cars number "023/555) engraved on it.
