Especially as those T&Cs seem to apply only to the Groupon vouchers. There are no such limitations mentioned on the web site (unless they only show up after you paid...)

Edit: after reading that thing over, it seems those who order straight from their website are actually worse off as they will not get to see those conditions until they arrive at the event :-/

However, given the locations, these appear to be parking lot events. That will limit how high you'll spin up the moter. (Unless you intend to show off your drifting prowess...) Short, tight courses tend to trigger the preservation reflexes if you've never done something like that before. OTOH, there's a good chance of collecting a few cones on the way, so that scratch & scuff waiver might be worth it.

IANAL and all that, but the terms are available on Groupon's site before ordering, so you're pretty much on the hook.

:-(

I have done track days before and having to pay for any damage is pretty much standard, regardless of who caused the prang.
