Could 80% not be easily done by yourself Paul. Check all tyres and pressures? Wash and Vacuum? Check all lights, levels, washers and wiper blades? Dont you do that already? Check radiator vents? I could even probably check my own drive shafts and CV boots, I know if my electrical devices are working properly. Lubricate locks, seems easy enough. Seems to me the minor service is good for changing oil if you cant do it yourself, but nearly everything else is pretty simple stuff imo.

Edd, you're absolutely correct. Even though I joke that I'm not capable of knowing which end of the hammer to use to check tyre pressures, I have done a couple of jobs on the 944, including clutch slave and rad hoses. It's not only lack of competance that stops me, but more the practicalities.
I'm a gardener, which means that I'm needing to work whenever the weather is decent. I'm not keen to spend a wet day under a car, and I don't have any covered area to use. I also have arthritis, and working under a car on axle stands is just impossible if I've got any sort of flare-up in my neck. I have limited tools, and what I own isn't always the best, so would need to spend on building that up (starting with a jack, gives you an idea how little gear I have!).
The other problem is what I can't do, or don't spot. When it's being serviced they are usually quick to find any faults, which I might miss, before they develop. Then, they also know how urgent something is, where I might not be capable of judging whether to replace now, or leave it a few years. If something I couldn't tackle cropped up, as it does every year, it'd be going in to the garage anyway.
It might seem excessive to pay a day's money to someone to change the oil and do a few simple checks and things, but in fact whilst I'm earning a day's money doing what I'm best qualified at, the expert is giving the car a thorough going-over. It's really the only sensible option for me, personally, and I just don't see it changing unless I had time, a garage and the ability to get the car up high enough to be comfortable. [&o]
