Purchased a second-hand Giant mountain bike from Mark. Highly recommended for anyone looking for quality bikes with a good price tag. Mark is very knowledgeable plus the bonus of being a genuinely friendly, pleasant man to deal with. No hard sale, proactively offered us a test ride and answered all our questions. I’m sure there are slightly better prices available on certain auction / second hand sites but the peace of mind gained from talking to Mark and buying through him was definitely worth the extra money.
