I didn't find one that I thought looked good enough to mount in the cockpit.
I put mine in the boot.
In the event of a fire I think the first thing I will do is try to get out the car then if it's still worth trying I will open the boot and grab the extinguisher from there. I never lock the boot or bonnet when I'm driving the car.
That's assuming I can get out the car anyway
Best thing really is to fit a plumbed in fire system with the tank in the boot and nozzles under the bonnet This can be activated by a remote handle under the dash.
