Going to be a tough one but T515 BJB will be coming on the market in a couple of months time - if you haven't seen it in person before on the few meetings that did go ahead last year its a very well sorted example. One of the very last pre-facelift examples of the 2.8 that was produced it has the M52TU engine and has only done 76k. Ideally want it to stay in the Z3 community so happy to discuss an early release before the general listing in a couple of months.
