We have a good little scene here in Vancouver too, but it's nothing like it was in the early to mid 00's. There's so many reasons for this:
The total number of MR2's on the road only every shrinks. Cars get written off, parted out.
Some just get don't get used as much as people get older and have less time (kids).
People are going out less as a result of social media.
People can't afford (as many) less practical (toy) cars than they used to.
The cars that are left are more often good condition & more expensive to buy, and therefore sometimes harder to find a buyer.
People like the new shiny things.
The new shiny things, by measurable quantities are better (mpg, speed).
Not wanting to deal with older car (high mileage) problems.
