Lots of the cars mentioned in posts above are going to cost you an absolute fortune to insure at 24 years old.
Your 2 years ncb are meaningless as you are already using them on your daily, you can't use them on two policy's simultaneously so you'll be starting from scratch.
Classic insurance is your best option if you're eligible for it, it might be a minimum age of 25 but im not too sure? Think the car has to be over 20 years old?
No matter what forum you're on, there is always so much BS on threads like this about how much it costs to insure cars. Of course you don't know until you get quotes but pay little notice to people who say things like 'i insured an evo when i was 22 for £300' etc
