Hey so I have a 2003 Nissan 350z I just bought it dude said it was good and it seemed

great but we have a lot of snow and it sits so low to the ground and the snow was dirty couldn’t even tell but I guess it has a small radiator leak, and if I drive it fir a good minute I swear it’s transmission fluid smell not radiator idk but I see smoke come out the front after driving it for a bit and yes I do refill the radiator. Or is it just the radiator. And transmission shifts great too

 

Welcome and I've moved your post to a more appropriate forum and deleted your duplicate thread. There's no way any of us can diagnose your car from behind a keyboard. You may want to find a good level surface to jack your Z up and check the tranny and radiator. You don't say how many mikes are on this car, or if you've got any maintenance records. But if there's no maintenance records, you'd be well advised to change ALL the fluids (radiator, oil/filter, tranny, diff and brake fluid) as a starting point.

 

Looks like a stagecoach with the sunken in Mazda wheels. Guessing you didn't pay for an inspection prior to purchase.
