i got mine out the passenger front door recline the seats right back.
If you get the right glue nice sharp stanley blade and a clean dry sponge it's easy.

1) remover roof lining
2) rip of old cloth
3) remove any loose old sponge (i brushed all mine off with a stiff coconut hair broom)
4) spray roof lining with high temp glue and leave for about 30 seconds
5) gently lay your new cloth onto the roof lining
6) press the new cloth down with the dry sponge this stops it getting finger inprints in the cloth.
7) once the cloth has been worked into all the corners etc trim it leaving about 50mm excess to fold round the back
8) re fit it the habdles sunvisors will help hold it all in place too.

about an hour and half tops.

But to answere your question i think 220 is a bit steep.

If you don't want to do it your self i would get autoflock(trader on here) to flock it, it will never sag again. If mine sags again i'm gonna get mine flocked.

do search on here about flocking it there was a thread a few weeks ago about it.
