Eurotunnel changing car?

[Mark.]

I'll ring them tomorrow but anyone got any experience?
If I book to go this Sunday online I need to put in my car make/model/registration number, so say it's peeing with rain and I think it'd be better to take a different car - how does that work at check in?
Random question I know but the day would be a lot better in a convertible if the weather allowed.

As long as its still a car they don't care. It might slow you down a little at checkin.

Did exactly this a few weeks ago as well as last year.

It just means that you have to type your booking reference number in as you drive upto the entry instead of it reading your plate. Plus it'll sync the reg you leave with when you come back in the opposite direction too!

Thanks chaps - I did look at FAQ but the Tempranillo must have obscured that line
