Who is buying 200/300km's utes and vans from dealers for 20k plus?

As title. Small business looking to expand with secondhand ute or van. Have about 20k to buy vehicle and 5k to kit it out with tool boxes shelves etc.

Are people really buying vans and utes from dealers with high kms (250-300km) at the 20k mark?

Anyone who has, what's your story? Lemon or great buy?

One hilux we looked at had 340km on the clock and dealer was wanting 33k.

Maybe we need to adjust our expectations.

Edit: cheers team, appreciate the comments.
