I don't think so. The car is in Wirral and Albs in essex.
By the way, I got a message from the seller:

car never owned by police. 2 previous owners both named on V5. Car failed mot on windscreen, rear shock absorber and rear tyre, all will obviously be rectified for retest on Monday, advisory on both front tyres. Done HPI check and i can confirm that this vehicle : Vauxhall Omega MV6 auto, registration W826MUY has never been subject of insurance claim or loss of any category, never been stolen / recovered, never been exported or scrapped, never been the subject of a vehicle identity check. I will provide a full reciept at time of sale.

After listening to all advices I have decided to pass on that one but somewhere deep in my head I am afraid that I will miss a bargain...

People keep saying that there is plenty omegas on the market, but I find it really difficult to find a decent elite FL for 1200 

I just got a message form the seller saying that this is probably not a car for me. I was asking to many questions obviously So I will do exactly what everyone suggested:

I will hang in and wait for the right car.

Once again thanks everyone for help. And if you will heard anything about 3.0 elite around please let me know
