Integral, what should you be able to do yourself?

Tomorrow, together, I’m thinking about whether I’m not getting an integral 8V. So, in the last few weeks, I’ve read a little googlet and foren on the Internet and I’ve heard that it’s quite care-intensive. What should you be able to do for yourself to afford it as a normal earner (no poor church sock, but lottery winning is not in sight -g-)? Candles, oil changes, etc. of course, you can do that, but you should have a lot of easily better be a hobby mechanic and can even remove an engine? thank you mfg max PS: What can a well-preserved integral 8V cost? I have seen that there are some who do not make the worst impression from 8 mille to have, or are those pure traps?
