That T4 in the end wasn't anything special. The conversion had been done to a good standard but overall let down by a rusty bodywork and loudly ticking engine so I walked away.
Tomorrow we're off to Norf Landan to check out an Outback (auto petrol 3.0) and a Passat (manual diesel 2.0 TDi). On paper I like them both equally. The OB will be more expensive to run and is 9y older. But is likely to be very reliable. Both have very clean MOT history and with similar mileage (95k or so). So it'll be hard to decide.
