Lowey,
When our youngest passed last year, we found that getting the right car and year to bring the insurance down was critical.
eg, a C1 on ’11 plate cost significantly more to insure than a C1 on ’62 plate, which is what we eventually bought. Same spec, same engine but a couple of hundred quid more for the older one!
The best insurance deal for us was to move all three cars in the household onto a multicar policy with Admiral.
As above, 6000 miles was cheapest point.
If she’s at uni’ then you might find that her uni’ address brings the cost down too if that’d be the address at which it normally resides overnight.
If done over the phone, then I found them quite helpful in terms of adding extra discounts if you just asked what might apply.
