It would look even better if they had filled it in right!
It should read just 'Vauxhall', not 'Vauxhall Omega 3.0 V6'!
Send it back for a correct one!
Also, just being pedantic (sorry!) having done a (sneaky) DVLA check, shouldn't it expire on the last day of November 1999 if it had a 6 month licence (or last day of May 00 with a 12 month licence) as the car was registered in June 99; as it stands expiring on the last day of December 1999, the car would have had a 7 month tax disc which as we all know wouldn't have been possible! Therefore the date of issue is 6 months too early!!
I see duplicate tax discs proudly displayed in cars at classic car shows, but the owners often get the wrong date on the disc, forgetting that the 1st tax disc would have expired 4 (depending on the age of the car),6 or 12 months AFTER the date of registration.
Having said all that, I agree - something looks missing without a disc. If you still have the last tax disc that was issued for your car before they stopped issuing them, then the first and last discs in seperate holders would be an interesting feature!
Incidentally, I still have all my old tax discs for every car I've ever owned - I think the oldest one I have is Sept 76!
