We are off to Venice next month and since we are going to visit a few places along the Brent Riviera a car is needed. Had my usual look at the links in here but came across a site we haven't used before. Here's the link https://online.atlaschoice.com/cars/ThankYou.php
Ended up with a week's car hire for £132 which includes all the necessary extras such as airport tax, crash damage waver, local taxes, etc.
Also just an observation but Hertz seem to have dropped their prices just lately as they are coming up second best on most searches so if you don't want to spend a few hours searching then you could just book with them. Hertz are partnered with Nectar so you can also get some additional points.
