Why Omega Caravan ? n couple of questions….

First of all, Moin, I own a Vectra B Caravan and am really very satisfied. But now, for professional reasons, I would like to buy a second big car and I thought of a Diesel Omega B Caravan: 1. Why can you recommend me a “? 2. Why did the ” with the price so lower? 3. What for Macks have the “, what do I have to pay attention to when buying? 4. 2.2 DTI or 2.5 TD ? 5. I heard the ” should have serious problems with the chassis, is there anything there, or only Humbuk? 6. Have 600€ ready, get something decent for it? 7. How much can he have down? Have so far only with the Vectra B can collect my experiences and am so familiar with the Omegas. Had the MV6 2 years ago for 3 months and was very excited…. Would you be nice if you could help me. Thank you in advance, Dominic
