Maybe yes. It is often the case that inc creasing the number of named drivers from one to two reduces the premium.
Likewise, parking on drive can lead to reduced premium from parking in locked garage !
I have 4 cars, all auto.
Lexus, Merc, Mazda 2
Yaris.
All fully comp, all Euro cover,3 have 2 named drivers and the Merc has 5 named drivers.
£900 total premium.
You figure it out, old pal !
