Until car manufacturers wake up, I would take the Keyless option off, makes it much easier to steal the car now.
The only advantage is they don't have to break into your house to get the keys.
Major security risk to keyless cars

Or put the £300 towards decent GAP Insurance.
Do you want to wait for a replacement car or not have your car stolen in the first place??
Do stolen and recovered cars go on the CAT database? If so I rather have a new one.
Also what if the crooks rag your car to bits, will it still feel the same when you get it back?
I personally would go the new car route 
Depends if its damaged or not. If its damaged then it will be recoded accordingly
If it's intact and recovered then it won't show on the database. If its stolen, insurance company pays out, and it gets recovered at a later date, it becomes a CAT X
More and more cars are stolen to order these days so they will probably drive it hard for a few miles before delivering it to whoever, which is not much different to anyone else with a performance car 'enjoying' themselves
