run away from the Berlinetta. Just my opinion, but the basic philosphy of that car was, ...we know that emissions have zapped the motor, so lets put every cool do-dad we can on the inside and people might not notice that it is a slug...
As a show/collector car, it may very well be worth it, as a daily tinker mobile I wouldnt bother, unless you have a ZZ4 crate motor and tranny laying around
