Engine Needed 1998 Gtv

Hello,

Does anyone out here have or know of a good place I would be able to buy an entire engine for a 1998 Alfa Romeo GTV V6 24 Valve.
The motor has the following indications on it:
ALFA ROMEO GTV AÑO 98 MOTOR V6 24V
The car plate has written on it:e3*95/54*0006*02

ZAR916000*06039773
ENGINE 16102

VERSION 916C1000 04.

Any help to [email protected] would be greatly appreciated.
Also, is there a really good website in Europe that can direct me to good used auto parts?

Thanks!!
Patrick
