On that theme, in Sept 2001 I looked at a 1 owner, original Irish 92 535i that Chris Fleming (previously of Sussex Terrace, near the old Burlo hotel) had, a 535i Sport in all but name. Asking price was IR£8750, iirc. Took a day or two to think about the leap from a 325i to a 535i and by the time I figured it was do-able, it was gone. The previous owner part-x'd it against a new Jag X-Type. I'm sure it seemed like a good idea at the time.
