nice tones and the lighting looks great for a car museum (was the ceiling all windows?). i like how you've managed to separate the cars from the ones next to them. my favorite is the jag xk 150, but the lotus looks pretty good too.
The lighting was superb owing to (as you have deduced) a glass roof. I was able to use my T50 with 200 ASA Fuji and just natural light. The building was originally some sort of railway building, but is ideal for taking photos of all the delightful cars. I could put a few more in if there is interest in them.
I had a Cortina too, but it was a '67 (or a '68 maybe,...cannae remember noo) and definitely not the Lotus variety. Great wee car, though. Very nice set, Stan. I for one would like to see more.
