The GNX yes, but the GNs and T Types not so much.
That’s the whole point.
They made 1050 TTA’s in 1989 only. A #1 Concourse TTA car is hagarty valued at $73k which is what #4 GNX is valued at. You can get a concourse TTA for the price of a shitty GNX and it will out perform and out handle the GNX. Plus, in my opinion, it looks better. Especially the interior.
But the GNX reached "cult status" a long time ago.
