eBay Z3 2.8, just put down a deposit

[spurs fan in a coupe]

Boot floor doesn't rattle, it creaks but check that, saw the starts of it going on a 2.8 recently, a few spot welds dropped in the boot, the hairline crack across the top of the diff hanger by the rear box box is the giveaway too.

Could be a loose heat shield or poorly fitting exhaust.

Could be a lot of things

May be a rear upper suspension mount that has failed they rattle when they give up.

Could be exhaust rattle

Check wheel bolts are tight and seated - after this check wheels are not rocking when jacked up.
