In the story of 200sx's, I've found another gem which might not be online for long.
Apparently well documented, facelifted 200sx S14 with stick shift and in the quite rare Racing Edition (basically everything better for performance driving) for 12 grand, with lots of wheels and spare parts. Not even big mistakes in the ad's spelling! The want is strong. Normally one like this would cost easily 15-16.
A 166 with a Twin Spark is not really that desirable, you can have a 2.5 or 3.0 V6 for pretty much the same money, you'll have more fun and it will be more reliable.
