Making progress on my 355CH search, few questions

Hi everybody,

I am slowly making progress. Actually may have found a possible candidate. It's a Dec 1996 which has received the 98 aero kit. Not factory but put together by the local ferrari importer. Aim is to convert to street use which should be possible. As I need to make an offer, I would like guidance on a few points:
- The car doesn't have aircon compressor anymore, apparently it has been replaced by the gearbox cooler. Is that the standard feature as I thought some cars kept the aircon ?
- Inside, the standard doors panel has been removed and there is a simple panel which vaguely looks like carbon finer with a simple switch for electric window. I have seen elsewhere cars retaining their original door. Is that a matter of latter cars having a different kit which includes lightweight door panels ?
- Airboxes have been removed and air pipes are connected straight to the intake. Is that standard as well ? I guess for road use I should add air boxes back
- Only issue disclosed by owner is an intermittent issue with ABS. light comes on sometimes. Switching off and back on clears it. Does this sound familiar to anyone ? if it does, what is the likely budget to fix it ?

Many thanks for your help

Best
