I'm after buying a family member a days driving in either BMW M5 or 911 at any central-ish circuit.

Has anyone got any recommendations?

I would like as much track time as possible, at least 1 hour or so. Not two laps like these £99 driver experiences you see around.

Budget around £400, is it possible?

PS- I've looked at the Palmer days but don't think the cars used suit our requirements

Thanks
