Are you maintaining it yourself ?, serious pain in the rs to work on for some simple jobs, used hard can get nearer 10mpg, I did ha ha but wasn't my car and I wasn't paying for fuel so didn't care.
Very well built, but do have some design flaws engine wise, don't like them myself, rather a cossie anyday, just running in, well trying to stay off loud pedal as not full power mapped yet but my 2wd sapphy just did 390 to a tank on a running in map but all local work.
