Sorry to bring the bad news, but insurance for cars that do not have lane assist, speed limit warning, auto emergency brake and all these other idiot oriented gizmos is 30% up compared to the "good old traditional" vehicles.
Pretty soon, this trend will reach UK, I am sure...
Paying 460€ for the Vitara that has all these and 640 for the MX5 that just has parking sensors (no discount).
