GTDI = Gasoline Turbo Direct Injection.
Looking through that deal, it's only for a vehicle that has an MSRP of $35,895 - which they only have one of in stock . The corporate Jag site lists the base XE MSRP as starting at $35,725, but when you try to build one, the cheapest you can get is $36,720, meaning you'd be getting the base of the base of the base. Also only 5,000 miles a year. And $4k down, which over a 36 month lease equates to $111/mo. So essentially you're paying $250 for 417 miles per month in a poverty spec Jaguar. Sounds like a really bad deal to me.
Though if I had to say something positive, at least they have the model in stock. Better than any of my experiences where the dealers don't stock the model they advertise. Or did stock it, but didn't bother updating their websites after selling it off.
