My sympathies to your brother, but he was warned
I saw a volvo 960 on an auctionsite today, 350$. The springs has been cut away and they've drilled the levelling system, but the straight six and gearbox is in good condition, so are the bumpers, headlights, bonnet, grille and side wings. I'm thinking about buying it, putting the gearbox and engine in my Volvo 240, and the bumpers, wings, headlights, bonnet, grille on my Volvo 940.
A straight six Volvo 240 and a Volvo 940 with 960 trim for the price of 350$ + whatever the cost of painting the parts would be.
It's a bad thing having to little to do during the workdays, I get all kinds of stupid ideas.
