Avoid like the plague. They will try and take advantage of your lack of knowledge to conduct major and minor repairs that are not necessary. eg. shock absorbers--when there was nothing wrong with them. Wind screen wipers were replaced less than 2 years, but apparently they were no good and had to be replaced. To add insult to injury they couldn't do the repairs, but had to get it done by a third party (Pedders). Though every franchise is different, I would avoid Castle Hill UltraTune because they will over charge and conduct unnecessary parts replacement.
