It wasn’t billbear’s car, it was mine.
Actually the original post that I responded to was the one from billbears to SoldierDad. SoldierDad said everyone should drive 55 and stop wasting gas and billbears told him to mind his own business (*grin*) and that his car did better at 70 than at 55. SoldierDad said, "BS" and GingisK responded with that nonsense about drag. I pinged you on the post because you had responded to GingisK as well.
BTW, my XK has the ZF tranny as well. I am sadly familiar with "the lurch." Thanks for the link, though. I think I'll start annoying the local Jag dealer about it. I thought I would just have to live with it.
