ok my 2 cents or the elephant in the room shall we say (imo of course!).
I used to post quite alot on here but in recent years I've stopped. And I KNOW I speak for tons of other members from 2007 and before who also stopped posting for the same reasons. Here is why:
1) It became very very clique in 2010-2014. Borderline bullying if you didn't agree with some high count posters that their cars were "Awesome" (to be fair they generally were, but the kits/styling etc. were naturally open to debate). If you said anything at all detrimental you'd be attacked by all the big players on here. Ironically most of these big players have moved on to other marques making this forum much friendlier.
2) After the above, many people just stopped posting their own projects or responding to others project builds for fear of criticism and have lurked ever since.
3) There are stand up people on here still who generally don't post much but now just watch/read and pm. Probably cause of reason 1. If you look at the amount of people viewing the forum at any point it hasn't really got any quieter just less people posting.
4) The long standing BS N/A supra bashing did nothing to attract owners who own the NA, despite being the same car. Again this just puts off a ton of supra owners from posting.
5) Cost of parts sky rocketing. So pricey now, there are far less projects being started as unfortunately this car has got to the stage where cost of tuning is truly for the passionate only. So less people buying supras for £2-4k and tuning them up on the cheap.
6) Simply far less of them on the road and being used daily = less activity. I hardly use mine anymore and most supra owners I come across equally keep them stored in garages now as they are worth so much and parts are expensive, they just aren't used much as a daily anymore.
