How about a fun diversion: are you a member of the Biggest Engine Club?
Here's how it works: if every car or truck you've ever owned had the biggest or most powerful FACTORY regular production motor available in that body style in that year, you're a member (i.e. for a '69 Charger, I'll accept the 440 (biggest) or the 426 (most powerful)). It's that simple.
I tried this on another web forum a few years ago and it went pear-shaped really fast with people talking about their 670 ci mountain motor Camaro or their VW Bug with a 350 Chevy or their friend that had a really fast blah blah blah. Cool cars maybe, but none of that stuff matters here. I'm more impressed if you bought a little Italian crapbox that was available with a 1.1, 1.3, or 1.5 liter engine and you went out of your way to find a 1.5 version. It has to be an engine that was listed in the factory brochure. Obviously if a model and year of a car was only available with one engine, then it still qualifies.
The more cars you've owned, the harder it is to qualify because, unless you were intentional about it, sometime in your life you may have bought a work truck or a daily beater for your wife to drive without worrying much about what engine it had.
So, think back to the first vehicle you owned and work your way up to today and count everything with a title or registration in your name: are you in? (Remember, biggest for that body style in that year.) If not, don't feel bad. I've asked a number of car guys over the years and very few could honestly say they did.
I've owned 15 cars/trucks and I'm still in.
(Bonus points if you've owned motorcycles and still qualify…)
(Club President is the one who's owned the most vehicles and still qualifies…)
