Feeling blessed..Greenhouse at last.

Well done!

Assuming it's a standard 8X6 size then the max length of the frame sections will be 8ft. They are fairly easy to take apart, again assuming the bolts are ali and not rusted up steel ones. Worst case you'll have to hacksaw some bolts off, unlikely but possibly if it has a steel subframe/base. Getting the glass out without breaking requires a bit of patience, depending on the make the glazing clips can be awkward. There are spares available online for the most popular makes so you can get new bolts, glazing clips, seals.

Take along an indelible marker and mark each section/corner so you can put it back together the same way. Take loads of photos prior to dismantling, it's then easy to look back to see what goes where. Keep the bigger bits in one piece to save time, e.g. the door/vents don't need to be completely stripped down.

I fitted a 8X6 in the back of our people carrier, you'll need to make several journeys with a smaller car. Use loads of blankets/cardboard to pack the glass and stack it on it's side rather than flat - it will transport better that way, several sheets tied together in a bundle.

The fun starts when you get it home

 

Good job

There's a few things to think about:
if you have a choice of sites align it North/South.
What sort of base for the frame to sit on? Did it come with one?
Have a concrete/slabs base or use soil?
How many vents? Get an auto-vent.
Make sure the base is completely square, measure across the diagonals and get that right before you fix the sides and ends.
Are you fitting guttering to catch rainwater to a butt? If so slope the greenhouse slightly towards the butt.

I'm sure there are lots more to consider

 

Hopefully you took some photos of it ? By vent I meant a roof window (although you may have a side louvre type vent too).

 

Cor, you're not hanging about
