ya i owned this car awhile back i got it with no engine. i sourced an engine off my mate jabrane thats also a member of this site.that engine had a new headgasket fitted (common 7m fault) and the turbo has been overhauled. its one off 3 mz21 soarers in ireland. THe one you have simon is the limited gold edition which had the tems suspension,tv in centre of dash,pegasus badge on bootlid made from ivory, climate control etc.it has been imported in 2007 by Neo as he once put pics off this car up on other car forum sites.
So far im liking the changes you have made to it and new rims should look savage on it.
If you need bodypanel parts for it or glass etc I suggest you try declan hicks in the uk, He also has a mz21 for drifting email is
