Not an import, but just paid £385 with elephant, tesco quoted £600 and were one of the cheaper ones tbh. I was with tesco last year, no tracker requested, although my mate was told he'd need one for his SLK....think it goes on where you live.
Couldn't believe £385 , well chuffed, especially as i've got points and a fault.
There is a thread in FAQs (i think) on different companies to try.
