I do my cars myself as well. Once a year service to keep it simple. Even my local Ford main dealer is useless. I've never really found a decent local garage that did good work at a reasonable price. I found 2 that did good work but were expensive....like uber expensive.
I do as much as I generally feel I can, but know my limits. Stuff that is a pig without a proper lift is usually a nope these days; exhaust work, major suspension work. I won't do cambelt, gearbox or clutch work. The older the car, the more confident I am I can fix it usually due to electronics typically being less complex and limiting.
I try to avoid starting any jobs on the cars where possible... I mean we don't need anymore rain!
