Do everything myself now. If tasks are complex, i do them in a DIY workshop with a lift and let the shop owner recheck my work to make shure everything is OK (he has some Porsche knowledge and always good tips and tricks when it comes to mechanical work). Also i don't have too much special tools, which i can lend there. Also sometimes it's good to have some helping hands. For example when removing rear axles…
And there is a saying: 4 eyes see more than 2.
