I bought a 2018 F-Type Jag from Hornburg Santa Monica and I was very impressed with all aspects of my experience, from test drive (they didn't bat an eyelid when I asked to test drive both the 3L and the 2L Turbo, despite them having to move quite a few cars around on their forecourt to make it happen) all the way to drive-off a few weeks later.
Everyone I interacted with was extremely friendly, helpful, and knowledgable, and my main point of contact, Kenny, was excellent and really easy to work with. He was very responsive via text, phone, and e-mail, and he enabled me to complete a large chunk of the paperwork prior to going to pick up the car, so my total time spent sitting and waiting was a little over half an hour or so (far less than you usually expect when buying a car!). It's nice touches like this that really set these folks apart from other dealers, because as a buyer I really appreciate them being considerate of my time.
The dealership itself is nicely laid out, very clean, and has a comfy waiting area where you can make yourself a coffee or grab a bottle of water. Parking on the forecourt is extremely limited, so finding a spot on one of the side streets is probably your best bet if you go for a test drive.
They really made the whole process of buying this car very pleasant and stress free, and I highly recommend this dealership to anybody who wants a Jag or Land Rover.
