Value S8 and questions about versions before / after update

Hello.

I think you can help me.

what an approximate market value should be an S8 Bj. In the case of the second half of 2000, the Commission has decided to increase the aid to the steel industry in the period 2000 to 2000 by almost 115TKM?

Condition good, well maintained, with the usual extensive equipment of the S8 as 6-speed switch..


In addition:

there was the S8 in old and new version (340 hp first, later 360 hp, from which year I unfortunately don't know exactly) - visually both before Facelift.

Can one assume that the update version (360 hp) has eliminated the "children's diseases"?

Do you still have tips on what to pay attention to when buying?

Maybe someone can help me.

Thanks in advance, greeting
Timo
