Frankie, if you want to live through the night, you will let me have a turn too.
Anyway, some cars that I've been beyond the exterior before:
Ford F-150 SVT Lightning (rode in this)
Alfa Romeo 8C Competizione (dealership)
'69 Pontiac Firebird (rode in this)
'06 Chevrolet Corvette (car show)
'10 Lotus Elise (dealership)
'11 Lotus Evora (dealership)
'11 Bugatti Veyron 16.4 (inside a dealership)
'12 Aston Martin V12 Vantage (car show)
'12 Audi R8 5.2 FSI (at a car show)
'12 BMW 760iL (rode in this)
'12 BMW 650i Convertible (rode in this)
'12 McLaren MP4-12C (car show)
'13 Mercedes S550 (rode in this)
'13 Lexus IS 250 (rode in this)
There are more that I'm not thinking of at the moment. Most of the dealership and car show ones just had open windows or doors so I could stick my head inside to look around.
