To euro_c:

Both the Astra and the Zafira are very good choices as a used car. The Vectra is also a good car but I do not recommend it if you are not too familiar with Opels..

Although I would recommend the Zafira since it seats 7 and has a dual aircon. Also, Chevrolet has complete know-how about the zafira with foreign technical update support and parts inventory.

Remember, these cars are very expensive when it was sold brand new. The astra wagon at P850,000 while the Zafira at P1,150,000...

PARTS: There are places in Banawe and Araneta Ave that sells Opel parts. They are abundant and are not really very expensive. They also have replacement parts that are all made in Germany so you are sure that they are really durable.

MECHANICS: Mato Tan's Fronte motors in Banawe are experts in Opel service and have a complete lineup of parts. There are also mechanics that I know from GM Casa that can do home service for the car at a very reasonable fee. Suspension, aircon and mechanicals are very simple and can be done in any competent repairshop. ex. autoteknika, speedyfix etc..

FUEL CONSUMPTION: The astra has a very good fuel consumption for a 1600 engined car. The zafira's 1800 engine is a bit thirsty but still very reasonable.

OPEL CAR CLUB: There is a Philippines based www CLUB OPEL PH with a forum about the cars and its overall ownership experience..
