Ah OK, it must be a different car then. Still, they're a lovely drive and I still miss mine after almost 5 years - though I do still very much like the Alfa 159 sportwagon (estate) that I replaced it with, and there's no doubt the estate is far more practical for my needs these days.
I used to average 23mpg from mine, less in town obviously, and about 28ish on a longer run. It was a wonderful place to sit and after a long and difficult day at work, with sometimes 300 miles of dark, wet, journey home, there are few cars that could have made a better job of that sort of journey. I had it about 4 years and did 50k miles, and the only that thing that went wrong with it, ever, was a completely dead battery after I left the internal lights switched on whilst away on business for a week.
When it's time does come to change the Alfa, I'll probably come back to Lexus, probably an NX or RX though, to keep the hatchback/estate practicality aspect.
