You'll struggle to get really good deals on SEs as they are built to order, i got about 5% off list with a few bits and bobs chucked in. It came in 2k more than a s/h van with a lower spec that had done 8000 miles...so residuals are good. Mine is actually on a lease scheme now through work as I could do a tasty bit of tax writeoff on it as i was moving back to the UK. It is the only camper on the company partner car scheme i am told ! Oh and mine was about 53 list, had a lot of options - man 4m, xenons, climatronic, towbar, rcd510 dab+, reverse camera, mudflaps (essential if you use a towbar rack as it protects it) and some others i forget.
EDIT: And there are a few around, we counted 11 Calis in 5 days not including a load of conversions we saw. There were 4 on the site in Kintail.
