Ghost is great if you have keyless entry, otherwise I can't see the point (and tbh, I kinda think it's possibly worse to have it) - it only becomes "useful" by the time they've already got into the driver's seat... So if it's keyless there's a chance they've repeated the key and not broken in - so ghost is great to stop them driving off. But, without keyless, they've already broken into the house and grabbed the keys (along with whatever else they want). If they REALLY want the car, they'll wake you up and "ask you nicely" for the ghost code once they've realised it's on the car... Seem to remember reports around Cheshire way a couple years ago, of thieves waking people up holding a kettle of boiling water to politely ask for car codes...
Previous car was a M135i (so similar hot hatch) and 4pm on a fri arvo (so broad flipping daytime) someone smashed the rear patio door, raided the house and drove off in my car (along with a load of bits and bobs from the house) - they also weren't bothered with my CCTV and carried on, just tried to raise an arm to try and block his face. Luckily I was out of the house, at the time, but it was bin-day and the bin was still out on the road with my car on the drive - so the police thought they took the opportunity to ring the doorbell and decide nobody was in, and give it a go... Car was found a few weeks later on cloned plates in a cul-de-sac about 10 miles away with a stolen Golf R and both cars had been linked with a load of burglaries in the next county - so it was stolen purely as a quick get-away car and left in a random cul-de-sac until they wanted to go for a nighttime raid in the next county... When the police recovered it, they said there was zero damage to the car's interior (so they hadn't stripped panels to look for trackers) - but they had apparently broken the front bumper, so had a nudge on something...
These days it's all about making the neighbours car more interesting that yours, and easier to take than yours... Avoid owning a A45, Golf R, (R)S3, M135i/M140i, etc... But, if you do, then realistically do what you can to make it less desirable and less easy to grab - (remove all markings to make it look like the fast version and try to make it blend in with a standard spec car), hide it in a garage or behind other cars on the drive, decent disklok is a must, then bollard on your drive, etc. Then think about your home and how easy it is to break in - make sure your locks are decent, have spiked anti-climb strips on the top of fences/gates, possibly security lights, etc. Finally, make sure your insurance is decent & valid (mod's declared) and you've got GAP cover too (and if you've got GAP then I think most refuse any mods).
At the end of the day, if they want your car they will get it... (hell, a neighbour of a workmate had their car lifted off their drive by a flatbed lorry with a crane) So, if they've gone to the effort of breaking in, then tbh I'd prefer them to just jog on and drive off in the car and I'll claim against insurance, instead of running the risk of them waking me up and demanding any codes...
Unless it's a Fiesta ST (known security issues with OBD2 port) then I'd honestly feel less likely the car will be stolen away from the house than outside it... (could always get keyed tho, for being a nice car in a bad area...)
If you "really" want a Ghost then why not just fit a killswitch? as it's far easier to deal with on a day-to-day routine and far cheaper:
