New Testarossa Owner

Hello everyone! I am fairly new to the Ferrari world, having only owned one for a little over a year. I am well versed in some half decent sports cars, but I think the Testarossa was the most exciting find yet. It was purchased from an auction, as are most of my cars, so I really have no idea where it has been, but it's a thrill to drive. I have heard many stories about major engine work and oil and leaks and what not....does anyone want to give me a headsup about what I should be looking out for? Thanks in advance, and I'm looking forward to being part of this community!
