Does the welding look a tad rough?.
Not a huge issue if the chassis is not exposed I suppose.
I bought a Caterham Seven in 1984 and sold it to part fund my Mog in '02. It had an Arch chassis and the welding was superb, the chassis looked as if it had been cast not welded. But I understand that there are complaints about the standard of welding on later Sevens, so maybe that's how it's done these days
I would still love one
