Would it have been an idea for your friend to have sat in the van before he bought it?
Yes, he obviously did, but didn’t take it out for a lengthy test drive, it was just a van to replace his old van, not a sport car after all. He may have assumed it was because he was unfamiliar with the van/seat, he could adjust it right later.. Does anyone really expect a modern vehicle to have a seat that won’t actual work for them?
Spooky, as Mac says, it’s not just about want to seat high, my friend has stupidly long legs. Though we’re of similar height, if I try to ride his bike, I’m on tip toes trying to reach his pedals!
