edit: a few points already raised above, but as this took so long to type I'm not re-editing itall, haha

Sorry to say my belief is the 'curse of the classic Vauxhall' is sure to play a part. Just look at the price of a Mk 1 Escort vs a Viva, or a Rover SD1 vs a Cresta/Victor 3300, or a Granada vs a Royale/Senator. For some reason, the populous as a whole don't seem to care much about old Vauxhalls.
It it Pop Culture, is it badge snobbery? I know one thing, it's certainly not the cars, the design, the quality of the product. I'm a patriotic Vauxhall man, and am content that the products from Luton have been consistently an equal or Better of Daghenam's since year dot. But some clever product placement by Ford, BL in the 70s has meant that a generation will forever associate Granadas, Capris, Escorts, Cortinas with moustached, womanising, hard-drinking, tough, uncompromising Coppers, Special Branch. Same way that all bad guys in a Bond film drive black German cars [notices own OOF profile, ermmm....

] it's in the public conscience.
Things like TV series Ashes to Ashes has a direct result on the value of Audi Quattros. Aston DB5s in Silver Birch are worth more than in any other colour. Same can be said for Gran Torinos in red with a white stripe down the side.
Reasons to Love an OmegaThe Omega, as the last rear-drive mass-produced saloon car by a volume car manufacturer, owned by the Royal Family, MPs, used by drug dealers, CID and the Police alike, replacing the legendary Senny. When the NCAP-led safety buzz kicked off in the late 90s, the Omega was one of the very very few cars to get 3 stars, and MANY manufacturers were left with egg on their face as their products were shown to fold in crashes. Omega didn't. 3 star is poor by today's standards, but one of the safest cars in the world in 1998. It outlasted all its other rivals, Citroen, Renault, Ford, Rover all making large executive saloons in 1994, by 2003... none.
I reckon that earns the Omega a place in Automotive History, and should help used/classic values. But even the Royale Saloon/Coupe, the rarest of the rare -beautiful to look at, strong, bulletproof engines, luxurious, smooth as silk ride, no bleeder cares about them/wants one. They're worth next to nowt, tragically. there's less than 60.
They'll always become 'Classic' Cars, as does any vehicle over the age of what, 30, 35 the recognised age? But many argue that is simply an
old car, and that a true 'classic' must have achieved something in people's hearts and minds. I've vote 'yes' for the Omega. Or at least it
deserves it, whether it will
get it is another matter, which only Time can tell
