Depends on dealer and yes depends if secondhand. We had salesman come for rides and when you notice something negative they correct it with some bullcrap. ends up pissing you off.
When we brought the Land Rover it was ex fleet. We went for a drive by ourselves then said not sure it fitted in garage so they let us take it home to check around a 60+ km round trip so gone a few hours Needless to say we brought it.
We were test driving last year with salesman in the back. I was asking questions, including "What is the turning circle on this?" Salesman replied "GOOD!"
LOL
They always seem to come with us. I can understand it, I wouldnt let one of them drive my car without me in it!
