imo all the 4 liter cars are appreciating now more than the later ones, even the later hi roof S2

well to be honest all the countach are on the rise

this is the best buy imo(strictly on investment):
1-LP400
2-LP400S
3-DD
4-5000S 2V carb
5-QV FI - 25th carb

if you plan to drive it a lot and have fun with it nothing beats the DD
