It doesn't say collect from a motorway junction, it's just an indication of location. When do you ever see a full address in an eBay listing?
I don't think there is anything suspicious about it, once you've unpicked the garbled description it contains genuine information. If it was a scam it would be fake information about a genuine Aston Martin, not real information about a fake Morgan! No scammer would go to those lengths for such a small reward.
