Do not go with tesco! worst ever for claims and will not pay out at all if they dont have to! just look at there reviews :( wish i had they were awful when i needed them.
Ive found admiral and elephant excellent when it comes to insurance on my non turbo hatch :) i pay £74 month ..... 5yrs NCB, 25yrs old, 7years full license, 1 crash and cancelled/voided insurance.
As above comments say shop around to high heavens to get best deal :)
