I recently won a rake of 4 triang mk1 coaches with comet sides already fitted and painted in choc/cream for £40 which is cheaper than the parts and today I won 9 airfix mk2d coaches for £53 which I also thought was quite good
it must be quite frustrating selling personal models via eBay but as other people have eluded to for the buyer it can be quite rewarding as I have just taken delivery of 4 comet conversions of triang coaches for £40 and they're quite well made.
