If you already have reason to believe the seller you are dealing with may be less than informed (or worse....simply misrepresenting a product) you should run, not walk, away and find a dealer you trust. The tractor might be a '92... I frankly don't know, as we do not deal in that model.... but if the seller is not straight with you about it being a grey market machine, what else is he hiding?
There is nothing inherently wrong with a grey market machine, but make darn sure the seller can cover you with parts. We get at least a dozen inquiries a week (it did use to me a lot more) from people with grery market tractors for which there is zero to very little parts support anywhere. The time to determine this is before buying. We have access to the largest aftermarket parts catalog there is, and I find no engine parts listed for the 215. Clutch, pressure plate, and TO bearing are all I find.
