Syncro engine conversion with 1991 Audi 100 2300cc 5 cylinder .
116,000 miles. All parts used were produced from the VW
factory for the South African market only. Awesome torque
and power. Body is excellent, as is the gray interior. Front and
rear A/C, power windows and locks.
Will consider Syncro Westfalia with bad engine as partial trade.
