Vacation to LA & Vegas - Where to rent car?

[yywwyy]

Hey guys,

I'll be on vacation at LA & Vegas (Through LAX). Early March, with my wife, no kids, 8 days. I'd like to rent a nice car during my stay (preferably sports car, convertible O.K.). I'm thinking a 981 Porsche boxster/cayman/ 991-911, BMW Z4, M3 (maybe even 335), or similar. Any recommendations on where to rent ?

Thanks in advance!

Nothing like putting the top down and cruising the 101 HWY at 3 MPH
