Bought a full 4 x set of mats for my 87 325. Black with red trim and under £30 delivered.
Once I'd figured out the right way to put them in (seriously, it's been a long night!), they fit great. Slightly too wide but not enough to worry me.
Recommended if you're in the market - and after speaking to them, if you use the code 'E30ZONE' at the checkout you'll get a 10% discount too!
