I won't be able to give you much info on leasing, but thought I would chime in here because I am in Nebraska and have some experience with Markel, (Land Rover of Omaha).
I purchased a new LR4 in 2010 and got a good deal on it. I was very satisfied with the sales team and the dealership overall. I did have a few trips to service with mixed results, but in the end I was very happy and felt like a valued customer every time I went in. Most if not all of the sales team has moved on since then including the new car sales manager, Phil Hatten. My Salesman, (Brad Freeman) came over from Baxter to Markel when they took over the Land Rover dealership. So, I don't have any names to give you.
My brother purchased a new LR4 from Markel late, last August and had to wait until late October for it to arrive. While I was able to negotiate a good deal on my LR4 HSE Lux, he got no deal at all and had to pay full retail. Which blows me away since when I got mine in 2010 it was a brand new model, and his is a 2015 HSE LUX that is now 5 years into the run. It just doesn't make any sense to me, especially when ordering and waiting for one to come in. No effort at all for a dealership to make $3k plus...
So, I guess I'm telling you this only because it pertains to the local dealer, (the only one in Nebraska). I don't have very high hopes that I will get a deal if I go back in for a Disco Sport, even as a return customer. But maybe it will be different.
Good luck with your lease; I put way too many miles on to lease a car these days.
