£15500 eBay Oct 2013 + £17995 eBay July 2019
my old HT3 UOV **2 (Sam's was GOV 132)
The above photo is of an Ariel described as an HT3 being advertised on eBay for £7250. I reckon it's the HT3 that I owned some time ago (see earlier photos) which I sold for around £5k. The ally mudguards have been swapped for a couple of plastic items, the engine panel featuring the HT letters has been swapped for a plain item and, being unregistered, there's only a very slim chance of proving it's a genuine HT3, albeit a 'tricked-up' one with a Bartram frame, some Steve Gagg goodies and various other upgrades.
P.S. I sold the bike in 2013 and the present owner purchased in 2016 for apparently £7250 - the same price it's currently advertised for. What happened during those intervening three years? More than likely that was when an expensive modern 'bitsa' gained a 1950's identity and instant provenance. Maybe a 500 masquerading as a 350. With its newly acquired DVLA recognition it would have immediately qualified for the Scottish Two Day Trial and increased considerably in value.
P.P.S.
May 2020. Bike now re-advertised on eBay for £6500.
June 2020. Now advertised by Stav Bikes of Chorley (a dealership) for £9995.
July 2020. As above.
On the subject of trials Ariels, here's a rather handsome specimen with an interesting reg. no., but is it really an Ariel, and is it really a pre-65, and is it really an HT? Hmm...
HT5 advertised in France, 2 Dec 2020 (see photo below), €10,500 (about £10,000)
