KEEP warranty. Do compression test. Then keep warranty justin case

If you wanted you could reduce the level of warranty, so you could consider just protecting the main drivetrain and engine, where most of the possible expense is.
However, with the way CSL's have gone up in value recently, it offsets the cost of the warranty. I would personally keep the full warranty as it will help you keep the car in tip top order and help it retain its full value, as I am sure any potential buyer would take the warranty as a major consideration when making their purchase.
