Volvo numbering system, 1970s: First number is series, second is number of cylinders, third is number of doors.
OP – feel for you. I’d’ve done the same. We went camping last weekend – the weekend full of thunderstorms – and I had reservations about going but it was booked and paid for. We put up a shelter to cook under, because cooking in a tent is stupid, and got a talking to from the site owner for having a ‘party tent’… soured the whole weekend more than the weather did. If the owners are Dicks it’s best just to leave.
