Powder as it will cope with all fire types, although if you're worried about mess look at a co2 or halon. BUT powder will beat them at putting out a fire.
go for a 1Kg one from halfords as any smaller will be pointless any bigger will just get in the way, and any fire it wont put out will be to big to tackle safely.

Halon is no longer an option. A compact CO2 will knock the fire down but rarely put it out. DP is the most effective but means that after use your car would require the valet of all valets.

Halon is the best extinguishant bar none, far better than powder.
One problem is it's a gas so in the open air it can blow away and the fire can then reignite, under the bonnet fine, in the interior fine, but outdoors it's a worry. The other problem is a tad more important, under the 1989 montreal protocol it's no longer legal to sell them as the gas used, BCF, is a serious ozone depletor, far worse than methane or CO2.
MSA did a back to back test with a fire under a dummy bonnet to assess what they'd use when halon was banned. To pass the test the extinguishers had to put the fire out in 20 secs. The results were something like powder 15 secs, CO2 14 secs, AFFF (a water based foam) 19 secs. Then they tried the banned halon which put it out in about 0.1 secs. So if you've got a halon one then hang on to it but if you're looking to purchase it's no longer an option.
If you go for powder then the main problem with their use in cars is that over time the powder can pack down with the vibration into a solid lump. Take them out of their bracket every few months, turn them upside down and give them a good shake and they're supposed to be fine.

I'm running the same extinguisher as Frayz, Si, and i've got it mounted to the boot lid. Its easily/quickly accessable in case of an emergency and i used the standard mounting bracket along with a velcro strap to hold it in place in case you slam the boot a bit hard. As for the mess a powder extinguisher makes, if you have a fire, cleaning up the powder will be the least of your worries. 
just because I have actually used a couple
