You'll be OK there mate, as long as you don't give it full throttle in top gear when you don't want it to kick down into third. Don't get me wrong Richy, they are really nice cars and the VVTi engine is excellent, I'm just trying to make sure you're going into this with all the facts.
Just out of interest, did you notice if the Traction Control went into Snow Mode while you were driving it? A lot of mph converted VVTi Supras seem to have an issue with that too, although it's only a minor annoyance.
Branners, Pete, et al, I presume yours do that too? (Can't remember if we've discussed this before/recently)
