Hi im currently looking to buy an Omega and this site has been highly recommended.
Im searching the small ads looking to replace my Mondeo ST and come back to Vauxhall.
Ive had corsas, astras and vectras and the family car is the Zafira so whilst im not doing the mileage I fancy an Omega.
On the mpg front I have just completed a round 220 mile trip between Ashford, Kent and Thatcham, Berks, using a whole mixture of motorway, congested urban and open rural roads, and returned 27.5 mpg in my auto 2.5 V6 Omega CDX, including having the climate control often set to 'low'. This I do not consider excessive mpg for this type of car with all the refinements it has.....and power! (YES, and I was frequently travelling at 80 mph+++ on the motorway (80% of the journey) sections.
Hope this helps make up your mind about the advantages of an Omega.
