I had a previous vehicle insured with YOUI, as they were the cheapest for me (~4yrs ago).
I can't stand the fact that they need to contact you for a price (after you have to give most details online, then confirm all details again on the phone). Do they think that they will have more people agree to their quote if they're on the phone?
I was looking for new insurance quotes a few weeks back. The quotes were around $450-600, YOUI's quote was for $1700 (also included roadside cover). Needless to say, I declined the quote on the phone, and they did call back a few times to ask if I'd like to take up their quote.
