There is a 3 bedroom semi next door. They have a driveway big enough for 2 cars.
The people who stay there regularly (more than half the week) have six cars between them.
They've just bought a rally car which appears to have no engine and is now parked in their drive. So that's them up to 7 cars. And a work van very occasionally too.
AIBU to think that this is a little excessive?
