Cant say I agree - had a bad experience
I'm afraid I can't agree with the other posters. I bought a car for my elderly father in law from SDR and had a very unsatisfactory experience. After paying for it in full over the phone using a debit card - which was fine - and after I had made arrangements to have it moved to my home (I live in Cheshire) by a transportation company, the garage rang me up the day before the car was due to be collected and told me that they had decided that they didn't accept debit card transactions over the phone and so were cancelling the deal. This was, I stress, after they had received full and clear payment for the vehicle. I was, as you might imagine, not very amused. Additionally, they had auctioned the car on ebay and in clear contravention of ebay rules they refused to accept paypal as a form of payment. After I complained to ebay about them they told ebay that they would accept paypal but then they refused to accept it when I rang to pay them. The car was legally mine, but they refused to release it. Caused me and more importantly my father in law untold stress. I wouldn't touch them with a barge pole.
