Yep, most likely stepper motor, nothing to worry about with MS
Yep perfectly normal, RTFM
Yes they are a PITA to bleed, get a Gunsons Eezibleed and follow official procedure, and you should be OK. On mine I spent 4 hours bleeding the brakes, and could not get a pedal, no matter how much fluid I ran through the system.... I gave up, took it for a slow drive and within 1/4 of a mile I had a hard pedal -that's 3 separate occasions and 2 different vehicles, and it worked.... odd one I know, but hey-ho
Not if presented for test running on LPG As it's a 93, I think you would if you presented it on petrol... so just don't
Anywhere from £500 to £2000 I would say, really depends on condition.... I will warn you though, the last of the classics seem a LOT more prone to rot than the earlier ones (pre-1992) and I wouldn't just look at the shiny paintwork and lovely leather and fall in love with it, get under and give it a THOROUGH inspection, the usual spots... sills, inner rear wheel arch, C-pillar, B-pillar, seat belt points on inner rear arch, front inner wheel arches, all body mounts, rear floor (lift the carpet), rear body cross member, front footwells.... the list does go on
Don't worry about the number of questions, and they aren't *THAT* much more complicated TBH
