Thanks guys. Some initial observations...
It drives very different to the MR2. A lot heavier steering as expected and not as direct. The gear change is not as slick either but I think that was partly down to the mods I did to my 2. It doesn't feel as nimble. The headlights are shocking and even my 2 had projectors which were miles better.
However the build quality is very good of the BM. The power is pretty immediate. The sound of the straight 6 is lovely. The inside smells like a cow and a nice one at that. The paint is far better, might seem a strange thing to say but you can just tell it's better. It has a boot. The suggested average mpg is very good for a 3.0l however I've not been anywhere near it yet
The mods have already started

so I've adjusted the headlights up a few turns. It's made a little difference but not much. I've ordered some carbon fibre black bmw logo door pins but I'm not sure about them now I've looked at them again, some LED error free side light bulbs which look a complete pain to get to!!! Philips xtreme headlight bulbs, Bosch twin aero blades, replacement rear number plate LED clusters although the old ones seem really hard to come out

only minor things but it's a start to making this beast even better
