Yeah, the Safari Tanks are pretty good by all accounts. The Husky I've bought already has one, so that saved me a bit more money there. I reckon the 450 could do 1/2 hour freeway stretches if you keep it in 6th as much of the time as possible and keep up with the oil changes. If you can find a suitable aftermarket oil cooler though, I'd consider it as good insurance if your doing long stints at highway speeds though.

If anyone is keen I'm contemplating doing the APC Rally this year (runs in May), as it won't be running next year. Looks like an interesting sort of event.
