In reply to IMA: Hi, we had a hatchbag boot liner for our estate (had a large Weimaraner...). The fit and materials were really good, the fasteners to hold the top of the liner around the edges of the boot (below the windows) were not so good, but this was going back 7 years so they may have improved. They were flat plastic hooks that hooked over the trim that the liner then velcro'd onto, but the velcro kept coming off the plastic hooks.
We got the liner and the fitted carpet bit to go on top of it. The dog loved it and would lie in the car given any opportunity...
Hope this helps.
