I have grown up seeing Jimmys all my life usually as government-issued contractor vehicles and I have had a thing for them wanted to get one when I grew up only to find I'm now too tall to drive one safely
The new Jimny seems like it's a bit more taller, since its exported to a lot of occidental countries. The bad thing is that this model has been so successful that the waiting list to buy one can extend to 6 months in some countries.
So is she implying that senpai was the one who invited the old friend (maybe out of politeness) or something like "you said no so why is she here anyway".
