Have got quotes on a rebuild for a 2.0 liter 74 starting at 3K to 5K. The 3K quote comes with a 18K mile warranty. But not sure of the mechanics rep (German Import in Simi Valley, CA) as got quote of 5K (and could go higher) from TREK in North Hollywood (as per this board it's a good shop).
Sure 3K is great price but does that sound too low?
