Are you assuming lotus because midengined sports car? The law isn't so distinct, they just mean passenger vehicle engines into passenger vehicles not like a commercial towing engine into an F150 or Mustang because they have different emissions standards.
The two tricks are fitting all the emissions equipment from the donor car and finding a donor car that's the same year or newer, so the '00 Celica mentioned above would be a no go into OPs '02 unless the engine is indistinguishable from a later year, which I think is rarely the case as they check known markings and I believe will plug into the ecu which will likely carry a date.
OP drive both before writing one off, I've seen a couple Z3s driven hard and they're not so shabby and the MRS didn't exactly set the world on fire when it was new. Also agreed with above my money would go into a Miata but to each their own, I'd drive the Z3 and MRS before making the final purchase. Good luck.
