Welcome along mate!
I know from a bit of insider knowledge (father in law runs an insurance group ) that if you've got a car c/d damaged vehicle any quotes you've already got will not apply, insurance companies dot like touching cat c/d motors if they can avoid it, and may very well load your policy as a deterrent. So just bear that in mind when your hunting for the car!
As for looking, download the free autotrader app for your phone and set it up with your price range, specs etc and then you can check what's on the market really quickly.
If you look up the model and spec on pistonheads classifieds too you can actually save the URL as a fav in your phone too, so that's another fast lookup of what's out there in your price range.
That's what I did :o)
hope that helps mate!
