There's always a huge issue with people who can DIY challenging garage rates. It might seem excessive to be charging £80 per hour, but remember they have rent, rates, insurances, staff costs, pensions, environmental disposal charges, advertising, any number of costs before they earn a penny. They have to use proper parts in order to offer a warranty, and have to add 20% to your bill every time.
3 hours on your drive for a belt change, if you're an expert with all the tools and don't charge, does make garage costs seem excessive, but I think it's an unfair comparison. Some of us have no option: mine is for health reasons an total lack of skills and tools, others might work long hours, it's just not possible for us all to be able to whack out a belt change on a 944 at the weekend, let alone have the skills not to break it!
