Westfield Sei.
What to Check Before Buying.
The Westfield Sei is a lightweight, motorcycle-engined roadster aimed squarely at track day enthusiasts and weekend backroad drivers. Built in small numbers by the British kit car specialist, it prioritises raw driving experience over comfort or practicality. Most examples are owner-built or workshop-assembled kits, which means build quality and maintenance standards vary significantly between cars. Buyers need to scrutinise each car individually rather than relying on model-wide assumptions.
⚠ Known issue
The Sei's kit car origins mean inconsistent build quality is the single biggest concern, with issues ranging from electrical gremlins to poorly fitted bodywork depending on who assembled it. Get the full picture before you buy.
