Thanks len, looks like I might have to get some more info on it's condition, is there any particular info regarding age etc that particually affect price?
Sorry for my lack of knowledge, but it just cropped up out of the blue after I mentioned my father used to own a comet, I've not had time to do much reasearch.
So much depends on the model, its provenance and then condition.
Is it an A (pre-war) a B, C or D?
There's quite a difference in value today.
Let's assume C, 1949/50 onwards.
Do the numbers all match, did it leave the factory the way it is now - if so, add a little
Is there any history to the mechanicals - what has been done, by whom, to what standard and when - if not - then you may have to do it all yourself - and a Maughan total Comet engine can take more than 2 years and cost more than £4K - great value - but you have to be aware.
Cycle parts condition - bushes, dampers, all the things that wear - what sort of condition, cause if you have to go through the bike again then that costs money...
I agree with an earlier post - if it is a straight, genuine, honest bike, all there (or almost all, and be careful what small bits are missing, they may be very hard to source let alone cost a fortune) and cosmetically tatty then it is probably in the £4-6K range in todays market tops.
Sadly - people don't seem to follow that logic and you do see the above bike selling for more - but buyer beware.
Then on the other hand a minty restored B comet with brampton forks sold for "just" £12K including commission at the Banbury Auction - and it looked like you would not have to spend a penny on it and it would run and run and run......
So you pays your money and takes your choice, have fun, join the club soonest and if you aren't interested in buying the Comet then do remember me, I've been looking for a little while and not yet managed to conclude a deal to buy one.
Vincents are amongst the best motorcycles in the world to own and ride in my view, I've only done 15,000 miles on one so am still a novice but I love it to bits (1952 Rapide).
Best of luck.
