Buyer’s notes
About the Lotus Seven S1
The Series 1 Seven, built from 1957 to mid-1960, was first offered with Ford’s 1,172 cc side-valve engine as the Seven F. A 1,098 cc Coventry Climax engine followed in 1958, and from 1959 BMC’s 948 cc A-series, as the Seven A.
What moves the price
- Identity: a car’s claim to be a genuine Series 1 rests on its frame number, plates and records.
- Engine: which of the three engines it has, and whether it is the one the car was built with.
- Originality: many have had replacement frames or been changed between specifications in restoration.
Before you buy, check
- Frame and plate numbers against the Lotus Seven registry’s records, and the plates themselves, since reproductions exist.
- Whether the frame is original or a replacement, and if replaced, when and by whom.
- A documented history, beyond a registration document.
