The prices you have got so far are great. My original plan was a concrete sectional garage as well and I had enough panels to make a single garage but wanted more and I was quoted £80 plus for each panel. I think it was a Marley one I had. Ended up giving it to a mate of mine, then had to help him build it.
Assembly depends on which manufacturer. The 'generic' ones are just mastic butt joints as is one of the main manufacturers. The other is a T&G arrangement similar to the Marley (which incidentally you can still get as well, but they were expensive too).

Foundation isnt a problem, will be 4" hardcore, 2" blinding sand and a DPC then 8" deep concrete, 12" deep round the sides to 6" out from the hardcore. When they build these normally the sections are free standing and then sealed on the inside with a 1 - 2" fillet of mortar to make it weathertight. I'm considering setting them in a 5mm mortar bed to make it weathertight, then internally I'll put down a 15mm screed and then 5mm of floor levelling compound to get a perfect smooth level finish. And then I'm going to paint it red with floor paint. 'Cos I've always wanted a red floor in the workshop :)
