Car hire in Sardinia

[ThunderSpook]

I am going to Sardinia in May with the family and was planning on hiring a car for a couple of days, preferably something roofless. We are based near Alghero in the North of the island. The car needs to have room for 2 small. Gilders in the back.

I found this company that had a Jeep Wrangler which looked ideal, but they no longer list it on their website:

I then found this company who also list one, but they are at the wrong end of the island so no good:

Currently the best I can come up with is a Peugeot 308 Cabrio from this company:

That doesn't really float my boat, does anyone know of any more interesting options that don't cost stupid money?
