depends entirely on condition and mileage, I've seen polo varients fully rebuilt and modified (underside too) for little over 5k, standard ones between 2-3k with low miles and good condition inside and out.
Also it's proving that it is genuinely one of few, I know they aren't exactly common cars but still people would prefer a rhd one. . Of course there is definitely a market for older vw's etc because of the cool factor but prices are only high on the models that people used to have back in the day or are "scene-cool" (see modified) being one of a few unfortunately doesn't make a car worth loads, Triumph Toledo's being a good comparison for age and sales numbers, there are little over 100 left on the road and they mostly hover around the £1000 mark, they are base models from their respective manufacturer as was the audi 50.
Consider how easy/hard it would be for someone to import their own and the costs involved.
I would say somewhere around the 3.5-4k mark because its an Audi not a VW and without the 1.8t possibly a lot more if the conversion is done well, ie smoothed bay painted/polished parts and slight tuning.
I've had a quick google at other audi 50 sales there was one in 2010 go for 2250 to the guys at autocar when they reviewed the new audi a1 another in 2012 private for 2500. There is one in the Netherlands for sale now at £3000 so compare the quality of your car to that and import costs.
www.carandclassic.co.uk/car/C688177I'm not going to lie to you, if there was a swap on the table because you wanted a golf mk2 with a 1.8t, I'd be interested haha! Maybe I'm lowballing it, maybe I'm not, who knows though I wouldn't believe what you read from the one in America, "12 left worldwide" I highly doubt that just because how large Europe is and the likelihood there is of someone to have kept one in their barn, keep tabs on ebay.de
In my eyes that which makes a classic car valuable come in this order:
Marque
- Motorsport pedigree (see e30 m3, escort cosworths, 1 off racers etc)
- Rarity now compared with how many sold (ie did no-one buy them or keep them going because there were better cars at the time?) If a car sold millions and now there are only 5 left because they were throwaway at the time, then yeah demand will be high from people who want to "relive their youth" so prices will be high (ie escort mexicos) But if no-one bought them new, not many people will want them now as young people don't necessarily have parents/grandparents telling them how good of a car it was etc.
- Spec? People (in most cases) hanker after the best ones, which is why mk1 GTIs are worth more than 4 door boggo mk1's
- Originality
- Modified? To what standard?
- Market trends, have magazines/youtubers all of a sudden coveted a certain brand causing mass awareness and value rises because people who didn't think they wanted one now do because they've seen videos etc of cool ones (see air cooled porsches - I think this bubble will pop sooner or later)
I'm not claiming to be a classic car value expert as every case must be treated individually but consider what information you can find.
If anyone has anything else to ad or has info contrasting to mine please feel free to ad, if I've said something stupid please correct me.
