I did a one-dayer for work today to Arcata, CA. Hwy 299 in Nor CA. About a 300 mile round trip through the mountains. A warm Fall day in the 70's. The GT ran great. Found myself using 3rd overdrive for a lot of the big grades. A nice in-between gear for climbing.
I saw a nice black MGB on the way over and a green Sunbeam Alpine on the way back. I waved, they didn't! :S
