none of the above, ive had 1 car wrote off which was about 6+ years ago IIRC, you only have to declare them for 5 years at the most, ive no points, car is parked on the drive, ive got about 6 years NCB IIRC
If you've got over 6 years no claims, a clean licence and are over 25 then sounds like regardless of driveway you live in a shitty postcode.
Have a look on here to get an idea.
