agree, the water was high. I would take the chance on the turbo, but not on a later model heavy with electronics. I doubt you could ever chase the gremlins away on that 850...Agreed. The VIN, 4290151, checks out as a LHD 2002 turbo.
Looks like the water reached the gauges.1502 - 2002 Turbo VIN numbers
