Advise Needed: Diablo Vs. Countach

I currently own an original 1980 DeTomaso Pantera GT-5. I am going to sell it and buy a Lamborghini. My budget is $90,000.00 or less.
I am looking at either a Countach Aniv or a 91 Diablo.

I would appreciate any feed back by those that have had one or the other or both on your feelings comparing the 2 cars for over all maintainence and driveability.

I intend to drive this car, it will not be a garage queen.

Thank you for your help.

Diablos power will beat it in any catagory, and also go past 200mph, and i heard the clutch is like too heavy in the countach, and the interior is kinda ugly too(especially on tan in my opinion), but any way is a great idea, and the countach is an attention whore when you back up(since you cant see , you have to open your doors up to see behind you, but i think that the countach has a nicer stock sound than the old diablos unless if you get a nice exhaust for the diablo. and its way easier to tune the diablo and you can even ask allanlambo, his diablo sv runs on nos and doesnt even bother his engine
