Car appreciation... the aesthetics, the engineering, etc

There's lots of different factors at play with insurance, old man cars don't always work if one major factor is skewing your premium.

@Sumo
NCD will always bring your premium down, that's the point of it, it's a No Claims Discount.

If a variety of different options didn't make any difference then might I suggest you're not being varied enough.

Trawl Autotrader/Gumtree/eBay for cars with number plates that you can put in the comparison site. Find:

1. New Economybox eg 1.0 Fiesta
   
2. Old man car eg 90s Merc 2.0, Volvo, Jag etc
   
3. 2-5 years old Ford Focus/Golf/any sort of estate 1.6 etc something you might drive
   
   

Then use two postcodes, your own, and try one just outside London eg RM11 1EX

Then try with 0 years experience, and 5 years.

Run through every possibility, it should only take an hour or so, and make a note of all the different premiums.

If you've got more time, try a 3rd postcode in the countryside.
