When we bought an Audi last year with PCP finance we took gap insurance but when we bought the 500c we paid cash and didn't bother. If you have finance on the car and it gets written off then you're left with an insurance payout that almost certainly won't settle the outstanding finance, which is why gap insurance is so reassuring. If you pay cash for your car then after a write-off you negotiate your insurance settlement and just go buy an equivalent used car with the payout and you're no worse off. Given that we're not accident-prone, gap insurance seemed like an unnecessary cost to us. But whatever you've done, I hope you enjoy your new car!
