The 80s are not too common here either, mine is only an HZJ so no turbo, but I've got used to waiting for it to get up to speed. IMO and at my age, I'm not looking to be the first at the next set of red traffic lights!
Many's the time I've had 8 bikes on the roof in the past, but not so much these days. A lot of the biking crew have got married or moved away, and biking is not so much fun on your own.
Downhill became my preferred mountain bike sport as I've got older (for obvious reasons). Here we've got circa 2,500m mountains with cable-car access, so it's a dream for a mixture of technical/fast/rock and grass downhill, love it!
