Have you considered a PCP deal on it?
It's not leasing, but it's about as close as it gets. Lower monthly payments due to the balloon payment at the end, and if you don't want to buy it at the end of the term you just hand it back.
It's also easier to get out of a PCP deal than it is a lease should you ever need to get rid of the car. You can either sell it and settle the outstanding finance, or you can legally hand the car back with no fees once you've paid off 50% of your contract.
If you're dead set on leasing though then it's obviously not for you.
My current car was initially a PCP contract.
Tbh the lease deals on the Cupra were just too good compared to the Monthlies on PCP and not having to pay road tax is a big bonus as well.
Seems like a few local dealers do have Cupras in stock again but they're still quoting prices far higher than what Nationwide were offering.
I'll give it a while to see it they shift, it not then hopefully the prices will come down.
