Paintshield: essential item, a lot of its visibility is down to the installation, so recommend doing the trip to Grantham to see Tom ! As for the line on the bonnet, it is slightly more visible on certain colours, and now that you have the choice, I'd go for full bonnet! I wish I did my bonnet when I did my bumper (1 week old car) as bonnet was getting a lot of chips, which I have touched up now that I have the full bonnet Paintshield
Tracker: if you are planning on keeping the car long term, get it! extra piece of mind (although some say they wouldn't as they wouldn't want a stolen car back)
