Re: any mechanical upgrades on phase 2?
Strange to say, the Phase 1 TS engine also sounds and goes better than the Phase 2. Some have suggested this is down to the 'fifth pipe' on the exhaust manifold, which is the Exhaust Gas Recirculation pipe. This was deleted in the Phase 2s and the job is done by the ECU. Sometimes, good old engineering is best done by just that, rather than electronic wizardry, which tends to go wrong anyway.
But I also agree, go on condition and service history, rather than tarty silver interiors. The leather seats in the Phase 2 are crap as well by the way, you sit 'on' them rather than 'in' them. The most ludicrous and 'unsporting' seats I've ever had the misfortune to sit on. They smell nice though, if you're into leather sniffing.
