Wow, you've kept really good track of everything. Your pic of the Triumph reminds me of my dad riding around in Triumphs and MGs when I was a kid. Maybe that's where my love of sports cars started. As a baby I rode in a basket on the back shelf of an MG, before people had car seats and stuff like that.
I just went to a British car show with him this weekend.
Enjoy the next year of your Boxster's life!
