I would go with the 940. Might try to talk them down depending upon miles. See that it is missing the alloy wheels. Can be found at the wreaking yard. If it's an "SE" It might have indipendent rear suspension, not sure about the wagons though. This will be a much better car then the 850. This was basically as good as they got, if it has the b230ft, this motor is fairly bulletproof. Good luck
