There are no daft questions here , but sometimes people who are newer to our cars make silly mistakes by not asking. There is a lot of experience here about Morgans, and most folk are very happy to pass own their wisdom.
The Series 1 Roadster (I assume 2005 is Series 1?) has a very devoted following , and in many ways is the pick of the range, so you have made a good choice.
The first upgrade I would plan would be the modified sump to give extra ground clearance , especially if you live in an area infested with speed bumps.
