All forklifts {and all designs of any product} have compromises in the design. Mengr should not try (and decide to demean, slander other brands than ones he has a fudicuary responsibility for) that any truck is better or worse.
The "track record" he may be looking at would be his own experiences with a unit he was never trained to work on. I would doubt that any principal for Clark Material handling would agree with him.

In my not so humble opinion:
Making statements based only on personal experiences, and not noting that this "track record" is only his personal experiences 'record', and not that of any official body, shows a lack of real expertise, and a lack of concern for telling the truth.
Almost everyone here thinks the brands they are trained on and familiar with are 'the best brand'.
now on to the question.
This truck is not a bad price for a good running truck of this size/capacity being a pneumatic, especially if it has GOOD 'solid pneumatic' {no air valve, higher $} tires see if the seller will put on new solid tires, but it is 'long in the tooth' and one that the hour meter reading may not have much to do with the life of the truck.
I would be cautious to post it here, if it was a -great- deal, someone will beat you to buying it, and this site has a pretty extensive listing of used forklifts, and people/companies who can provide used forklifts at reasonable (equal to the condition) value.
I would want to do a compression check, have the fluids tested, and have someone that really knows what they are looking at to look over the mast and forks, and if it is a Mitsu motor, go ahead and change the timing belt.
The seat will have to be replaced with one that has side or shoulder restraints to meet US federal government requirements about equal safety in replacement parts.
