The Appeal
Anyone who knows their Vauxhalls will be well aware that the letters 'SRI' and 'GSI' mean a great deal when it comes to performance. This Vectra began life as an SRI, denoting a few sporty extras, but it has since been upgraded to GSI spec with notable performance hardware.
This car has been professionally converted from an SRI to full GSI Phase 1 specification by renowned Vauxhall specialists Courtenay Sport. The comprehensive suite of performance upgrades, including Courtenay Sport camshafts, a lightweight flywheel and clutch, and engine mapping, elevates this Vectra beyond even standard GSI specification with impressive power output of 222bhp. and thoughtful modifications.
This represents a rare opportunity to acquire a meticulously maintained and enhanced example of an increasingly scarce performance Vauxhall.
