Tried both versions, no difference in quoted price.
What were the quotes though?
£179 for protected fully comp. with Hastings but once I get a registration number Saga will be cheaper, about the only advantage of being old is car insurance. 
Bloody hell dude! Less than £200? Wow.
... Can you be a second driver on mine when it arrives? 
Don't think that would help as it's always based on the youngest driver. Saga should be around £150 as that's what they quoted me for a new Fiesta ST which I think are the same insurance group.
it's based on risk not age at least not entirely. one person driving a car all the time is deemed more of a risk than two drivers who may share some of the driving. in theory your risk is halved giving lower premium.
Yet when I added my wife (who is older than me and has more NCB than me) to my current policy those fatherless sons at Avivia bumped the price up! I specifically pointed out that this meant I would be driving the car less than if I was the single driver and that they agreed she would pay less as a single driver, yet they are so f**king dumb they couldn't see that contradiction in their thick little heads, and no amount of explaining yeilded anything but long and tedious quotes from their terms and conditions or some other bullsh!t document that negates their need to use their brains. Yes I hate Aviva. Don't use them, trust me on this!
Apologies for curse words, but those guys make me mad.
