My '97 had only the tilt feature, actuated by a little lever on the left side of the steering column. (Since you're UK, that might well be on the right side -- between the steering column and the driver's door!) The lever was behind the turn signal/cruise control stalk.

A telescoping wheel, in contrast, was an option on the '97, but probably only seen on the higher-spec models like the C280 and C36.

It's a fun car and eminently sensible too, esp. with a manual transmission, in these times of high petrol prices.
