Interstate GL1100's are the most commonly spotted variety. This model spanned the whole production run and most GL1100's sold were Intertates. If there are any clean ones left, a 1980-81 model should get around �2,600 and a 1982 with the smaller wheels about the same, probably because the plastics hide the obvious difference in wheels and tyres. The 1982 Aspencade is sought after and a fully loaded one will easily exceed �3,500. The 1983 Aspencade is highly lusted after. This was the ultimate GL1100 and the extra refinements mean that you can expect to be relieved of up to �4,500 in a private sale, perhaps even more for this rarest of the species. Various colours were available for the GL1100's, Wineberry Red, brown, blue, black and a very rare green. The most popular colour is Wineberry Red and a clean example in this colour will always be worth a bit more and as such will be easier to dispose of when you get too old to hold the thing up on the road. A tatty example (cracked plastics, faded paintwork, engine paint flaking, rusted exhausts etc) of any year can be had for as little as �2,000, but if you want to bring it up to scratch it will cost much more than buying a clean machine in the first place. At 2005 prices, try �250 for a full badge set for example, or �700 for the upper fairing. It should be noted that in general, Goldwings with lots of accessories don't always fetch more money than a less loaded machine. Many folks spend several thousands of dollars or Euros on extras, only to be insulted by the deal offered on a trade-in or from a buyer. Some extras will appeal to particular buyers and will prompt them to pay a bit more, but you will never recover all the cash spent on accessories when selling a Goldwing. The real value is on the machine itself and if a seller intends to buy another Goldwing of the same type, it would be wise for him or her to remove whatever extras that can be fitted to the new machine. The recent (late 2004-2005) price drop of new Goldwings in Ireland (due to the low dollar) has not affected the prices of GL1100 models. They are so old now that the prices are unlikely to drop further any time soon.
