I wouldn’t worry about this harming values, and question whether the warranty was ever transferable? The product is arguably the best of UK products, and AT claim on a marketing video to have 25% market share, in the UK at least they are highly regarded. The prices will hold as the buyer still gets a great van.
But I think an understanding of importing and warantees might help.
My experience as an importer of a major Japanese electronics brand says it is unlikely that there was any contract between AT and AMH. For years there were two or three persons in NZ importing AT motorhomes directly from AT in the UK. I would suggest that if you front up at Grimsby tomorrow with the money they will sell you ten motorhomes.
My experience with Japan was that at anytime they can and will take the brand off you. For this reason when trying to sell an import business there is no ‘good will’ factor as the product your business is built on is not securely yours! You can loose the product tomorrow!
AT are not Toyota nor Mercedes nor Fiat, not a major vehicle manufacturer. Most class A or class C MH contain three parts, a Fiat cab unit, an Alko Chassis, and a plastic house box. All separately manufactured by three companies with three warrantees.
Most manufactures don’t pay for warranty repairs. They don’t even pay for the parts, to do so would be a logistics and admin nightmare. In most cases they give a parts allowance equal to a percentage of the ex factory value. So for example I was selling an item that retails in NZ for $1000, we were credited $7 to our parts account to cover the warranty. I’m talking about a very BIG brand. We maintained a parts inventory for the life and longer of the product, and we paid the service department labour from our sales profits.
I would imagine that most Motorhome warranty repairs here are made by the importer/reseller. Many parts are interchangeable between brands, and many parts are easily repairable so any back yard dealership can handle habitation repairs.
We are very lucky to have Fiat warranty our MH cabs. Most automotive brands do not cover private imports. I suspect Fiat do so only because they sell cab units to about 100 MH manufactures, and so the “good will” is significant. They probably found it so complicated arguing over who pays for what that they simply built the service into the cost price and offer a blanket warranty.
Generaly there is no such thing as an international warranty, even though the retailers in Hong Kong and Singapore told you so thirty years ago when you shopped duty free. If you are ever tempted I suggest calling the NZ distributor and confirming.
I feel sorry for those of you who may get caught out on this, but as others have said, best to move on, you may never need warranty support.
