As MateyGuv said go with the Clifford 2.1 alarm upgrade. I had to have a Clifford Avantguard 5.5 fitted as the local lads took a err... liking to my car!
Whatever you have fitted make sure the installer has a good reputation. I had mine fitted in 2010 it died a death less than a week later leaving me locked out the car!!! Got the installation company to come out they had to reinstall it a further 2 times and then it was still dodgy. Only 1 door locked or opened, sometimes it wouldn't respond at all and I couldn't get in the car!!!
It finally packed up less than 2 years after installation... The company had installed the siren under the bonnet and drilled under the scuttle panel and fed the alarm wiring behind the dash, over time water leaked in and shorted it out!!!
Well done BSWC Auto Security!!! Avoid like the plague they had premises when I had it installed now they're just mobile, refused to come out and sort it even when offered money... Just shouted "What the bloody hell do you expect us to do?" I had to get a auto electrican out the Yellow Pages to come and cut it out the car! Worst installation he'd ever seen the alarm brain and remote start module were taped together just loose, wiring was wrapped around steering column and was chaffed (could of caught fire) and they'd broken the trim all around the headlight switch and superglued it! Not what you expect for £700
