Welcome!
There are a few on here who have very detailed knowledge of these vehicles and will suggest seemingly illogical (but almost always correct) diagnoses for your problems.
Take them seriously, they know what they are talking about. You will not get thoroughly flamed for disregarding their advice, but you may suffer a mild flash-burn.
It should all be taken with good humor. These are quirky cars and some of the members here have (literally!) decades of experience with their quirks. They have seen what happens when the wrong pressure plate is installed, and it's not pretty. So, even though your dealer might assure you that this is the right replacement pressure plate, trust the combined wisdom and experience of those on the forum. Get the right one from Pete at RS barn and save yourself the time and cost of doing the job twice.
There is a thread on here for new owner advice, take a look and ask questions if something doesn't make sense to you. We have all been there.
Welcome to the forum and welcome to the learning curve.
