when I was 19 I had a 5dr mk2 gti, totally standard with a cat2 imob and I was with Tangent. I was paying ?1450 TPF&T (they added ?50 when I switched to my current golf cos it was a 3dr. I told them it was standard too)
I wouldn't advise you go with them as they're complete f**ktards, but if you want to take a chance to get a NCB then they were the cheapest. Just don't try and make a claim.
Just try everyone. HIC do some good deals, but you'll have to settle with TPF&T until you get some NCB built up.
Always best to go on your own really. NCB makes a load of different to your premium.
