Recently purchased a Spider through ebay (based in Devon!). The car was picked up and transported by Paul Devlin Car Movers (based in North Glasgow). Cannot reccomend the guy enough. The total cost was £350, which was some £3-400 cheaper than other quotes I had. I also looked into hiring my own transporter, and inc petrol costs the job would have cost me £270.
He also helped in the handover of the purchase cash, and ensured the V5/documentation was all in order.
Just in case anyone is looking for a similar service.
