I'd have to agree with salesmaster- having a dealer come in & give an assessment by accessing the on-board computer would be a good idea. Now that the machine is yours at least you'd know where you stand with it & could budget accordingly.

The only thing I can think of as far as the leak is that you state that it has always leaked ( at least a little) as long as you've owned it but now it's getting worse- perhaps if you read the warranty that specific issue is not covered because of a "pre-existing condition". I have learned the hard way that selling a truck with a known issue which both parties (me & my customer) agree to can turn ugly very quickly when the issue gets worse. Suddenly the lower price they paid is a distant memory. It's because of issues like these I no longer sell forklifts.

I don't know if 25 grand is a high/low price for your unit, maybe someone could chime in & give some guidance in that arena.
