Since you were all wondering what MY opinion was on this matter:
1) There are a LOT of Porsches in Vancouver. 2 million Boxsters and about half as many 996, 400,000 air cooled 911 made after 1973, and about as many 944 and 951. Some 928 (I guess) and there must be Cayennes too but I'm getting really good at blocking them out. Waving at every Porsche is just not done. Even a guy driving the same model and colour car as you doesn't always wave. Funny enough there are very few early 911, and even fewer 914.
2) The only 914 I ever drove was in an autocross. It was slow and sloppy. An entirely lackluster and uninspiring experience. I know it must have been set up all goofy, but what killed me was how enthusiatic the owner was about his car. If I ever see a 914 on the road I will wave crazily. From what I gather from this thread I guess I can expect a "my penis is bigger than yours" look back. There seems to be a lot of talk on the 914club board about penis size. Good for them I say. If I had a larger penis I'd drive a *****ty car too.
3) I get a lot of waves from water cooled VW owners when I drive my Mark I Jettta. It has sport springs and a header and is WAY more fun to drive than that 914 I drove in the AX. Come to think of it, the Jetta is kind of a beater which might explain the success I've had "with the ladies" since I bought it.
4) Too bad about those 996 and Boxster engines blowing up all over the place. I was genuinely looking forward to buying a used 996 and "clusporting" it one day. Maybe the aftermarket or whatever will remedy the problems, but there sure seem to be a lot of them. 996 owners don't wave, or if they do I don't notice.
Thanks for asking for my opinion - I feel better.
