Paul – as others have said, your lease end date is 3 years from the date you took delivery of your current car, not when you ordered it. Whilst you can order your next car 3 months before then, if it is a car that is in stock, or comes super early, you cannot take delivery of it until your full 3 years lease is up. If your new car takes longer than 3 months to arrive, your current lease is extended until it arrives, but the new car will still be a full 3 years from the date you take delivery. Given the lead times on many factory orders these days it’s a shame that the 3 month order window isn’t extended by a month or two. We ordered on Monday and it could take 5 to 6 months!
