have not owned a sports car in over 35 years.....i had a Triumph TR6 long ago.....Looking at Z3.... however sat in one the other day & i barely fit....had seat all the way back & head room/top was about an inch....That was not a problem......However getting in & out with the top up was not real easy.....Also with the top down it appeared the top windshield support was obstructing my view?........i am 6.1 ft...... I'm reading/hearing about things that can be done with the seat to lower it....... however order to do this I would need to purchase a z3........ also sat in a Z4...... it appears all these issues went away.... However I'm just not crazy about the Z4 body....... my heart with the Z3 body...... comments/thoughts always welcome......
