Does this affect the insurance premium? They don't need a lot to try to duck out of paying up on claims! :-?
If they think you have a GLS when in fact you have an Elite, do you think you will be getting Elite money if you have to claim?
Likewise premium time, you ain't getting insured for GLS money when you have an Elite.
As always, the onus is on the policyholder to ensure all details are correct...and there is no lawful getout clause from that.
Correct K, and the time to check that the insured vehicle is correctly specified is now and not in the event of a claim. 
Absolutely Zulu.
When I first covered our CDX, it came back as a CD.
Mistake duly pointed out...insurance asked for an extra £24...I told them to go f**k themselves and listen to the tape as I clearly stated CDX in the first call.......7 days later I get the letter "Dear Sir, we f**ked up....you are now covered for a CDX and there is no extra premium,,,thank you for your business".
