If there is a link that shows the tractor you are considering, please post it. But, let us know what tires, extra features like SSQA loader bucket, rear remotes, etc., it has, and maybe we can stick our necks out with a "value". If it is clean, well maintained, and you like it, it is possibly worth the asking price, or at least making an offer on. What else is out there for around that price? I wouldn't let the age be an issue is the tires and hoses aren't cracked, and sunlight is usually the culprit with that.
The
L3750 would be a Grand L, so it should have some nice features. However, Tractordata says the
L3750 was made from 1984 to 1990, so something is amiss here... maybe you listed the model number wrong?? I'm thinking the poster above nailed it, since I do see a tractor that fits the description perfectly for sale in PA, except it's a
L3710. If it's the one, then $16 seems fair- this tractor looks, as the ad states, "showroom new". In fact, as clean as it is, I am surprised it hasn't already been snapped up.
