The Cobra was sold to a Bromley-based buyer for £360,000 including premium.
6107 is the first ex-works coil spring 289, leaving Thames Ditton on 11 November 1965. 6106, the factory demonstrator and the first 289 Sports completed, was finished a month earlier and road registered by AC on 13 October 1965.
The rectangular tail lights are no mystery at all: AC used rectangular tail lights on all leaf spring cars, and on all coil spring cars until 24 November 1965. Thus all 427s up to CSX 3200 have them, as do the only two coil spring 289s completed by that date.
