Most jobs are doable on the drive way. Don't really need any special tools, a good jack, axle stands (best to have four axle stands).
I've swapped exhausts, suspension, discs, callipers and even had the engine out on the drive way.
Biggest job is prob replacing clutch and would say get a pro to do it, as it is a massive job to do, have to remove a fair few bits from the engine bay along with prop shaft, drive shafts and gearbox.
They are not any harder to work on than "normal" cars. It's just that the engine bay is pretty cramped so access is the biggest issue.
