Hi Dinky
I did some on line research a short while back when I was considering chopping my T2 in. I found only one Teranno, a late model 3ltre I believe, with cruise control. That was out of about a dozen post-2003 (?) models. The advert, I think it was on Auto Trader, didn't say whether it was an optional extra or after market add on. Whatever - they are a rare beast but they are out there, if you're willing to wait. Keep the thread going, I'd be interested if you find one as I'm still loosely considering upgrading, but not this year.
Regards CL
