Hey Stewart, £1500 is pretty good as is £1250 for a 12v. The 24v is certainly faster and as a later model came with a few upgrades (extra wood, LSD etc. I think). I'd looked at a few 24v before buying my 12v, but they were either too pricey or dogs. If you can verify the 67k then it would be worth the extra £250 (providing age, condition etc were comparible) but I'd rather have a 100,000 mile 12v with full history than a 67,000 24v without.
