What to Check Before Buying.

The Westfield Xi is a lightweight, track-focused sports car built for pure driving thrills. As a hand-built specialist vehicle, each Xi can vary significantly depending on build specification and previous ownership care. Buyers should pay close attention to service history, structural integrity, and any modifications made over the car's life. These cars reward proper maintenance but can be costly to put right if neglected.
