I am 25, 4 years NCD, I have a LCR 225, all mods declared. With this insurance company they charge you on BHP not mods. Im covered upto 280bhp and pay £570 fully comp a year!
I can add literally any modifiaction to my car and it wont cost me anymore on my premium unless it increases power to over my 280bhp im paying for. Any cosmetics, splitters, audio, wheels etc are all free just have to let them know its on there and can add at anytime.
Also my NCD is on another car and they mirrored them.. As in they have put I have 4 years no claims on my policy even though they are actually on another car i own. All I had to do is prove I had them with my other insurer, result!
Top service and excellent prices, my fully comp covers the lot aswel, windscreen, keycare, drive other cars etc.
